Geometric theory of the threshold of transmission capacity

.,Periodical Radiotekhnika., 10, 37, Jul 55
Abstract The limiting factors of sigma transmission in a
co=unicatigns
system are evaluated on the bPSiB of the geometric theory. The
limiting transmission capacity of a system is defined as the
greatest awvnt of inteUigance that can be conveyed to the re
ceiving end of the line, maintaining the lowest desired prob
ability of error. The transmission capacity approaches zero as
the level of noise approaches that of the signal. Reliable re
ception for mall increments of signal over noise require the
use of special methods of reception, such as storage and correla
tion methods. Graphs. Two references; one USSR.

TITLE on the Question of the Geometric Proof of SHANNON'S Theorem.
PERIODICAL Radioteohnika, 11 fasc. 11, 516 (1956)
Issued: 12 / 19
In the course of previous works (Hadioteohnika, fasc.2 and 7, 1955)
the
authors endeavored to prove the theorem on the penetrabilitj limit
geometri
cally. According to SHANNON this theorem is: C  F log + Pn
2 Pri
P here denotes the average power,of the transmitter I P Ti the power
of the
perturbation in the stripe F, C  velocity. In the present work the
theorem
is presented in SHANNON'S formand also geometric proof of the second
state
me4t made in this theorem. It wasfound that SHANNON failed to take
the follow
ing into account: Even in the case of the densest arrangement the
coefficient
of the filling up of the space by nonintersecting spheres is
diminished if
n = 2FT (T  time, n  dimension) increases, and at n ;~ oo it
tends towards
zero. The authors corrected this error committed by SH ANN ON and
obtained an
exITession which deviates from'that of SHANNON: C ~* F 11og (l + P
The difference between the two formulae is very essential in the case
of com
parable P and P , namely just in the case of such conditions as are
of par
ticular interesp in modern radiotechnology. On the other hand, SWNONIS
formula has been generally accepted. This contradiction could be
explained by
Radiotechnika, 11, faso.11, 516 (1956) CARD 2 / 3 PA  1705
two assumptions: 1. The limitof penetrability cannot be attained
by means of
a receiver that is ideal in KOTELJNIKOVIS sense. 2. An error was
committed in
setting the_,Feometric problem to be solved itself. Further
investigation
showed tLM'f the statements made by SHANNON contain a further
error: the con
dition that spherical spaces of indetermination do not intersect.
I'a their
previous works the authors adhered tothis condition from which
they concluded
that SHANNON'S formula is wrong. 'What is true is only that the
formula cannot
be obtained on the basis of geometrical assumptions made by
Shannon himself.
It is shown that the task is confined to investigating the
probability of the
error on the condition that.the spheres partly intersect. On the
basis of a
simple example the authors show that, spoken generally, it is
possible to ob
tain any small probability ofthe error also if the spherical
spaces of inde
termination intersect, but nevertheless no conclusions can be
drawn with re
spect to relations for the case of partial intersection, for here
the densest
arrangement is concerned, the geometry of which is not known.
Therefore, only
an approximation method can be applied. By doing so, the authors
eventually
obtain the expression: ~ < log (1 + L_ ). The right part of this
expression
F Pn
,is the penetrability limit according to SHANNON. Unfortunately,
the authors
cannot carry out proof to the end and are unable to replace the
sign of in
equality. It would suffice were it possible to prove that the
assumption on
the basis of which the authors obtained this expression is
asymptotic. The
Radiotechnika, j1j faso. 11, 516 (1956) CARD 3 / 3 PA  1705
authors regret not being in possession of this proof. It would
be of im
portance because then not only WONOWS theorem could have been
proved
geometrically, but it would have been possible to show whether
the
limit of penetrability can be realized by means of a receiver
that is
ideal in KOTELJNIKOVIS sense,

This relation for a coupling system for codes

determination of S(velo

only in those cases
in which the signals f are on the surface ofthe

situated at the ou,

ABSTRACT: It is shown that the sending speed of messages in non
uniform binary notation may be significantly increased
by a preliminary recoding in terms of a homogeneous
binary'codel,the length of which depends on the
probability p in the first equation at the top left
hand side of page 76. The information per symbol of.an

by 1) and this is plotted in Fig 1 for m = 11 2, 3t 1+
and 5. For each value of m this expression goes
through a maximum ata certain value of p. The position
of the maximum.is.clo.ser to p = 1 the greater the value

vector). The treatment is routine and of textbook type;
the last section (Section 6) deals with particular types

TITLE: Antifading cod ing
PERIODICAL: Elektrosvyazt, no. 4, 19601 3  6
TE(T: A method of signal transmission is described, using correcting
anti
interference codes and allowing to enhance the reliability of
communications in
the presence of fading. Assuming that the transmitted communication
is coded by
ndigit combinations of'a uniform code, a group of N such
combinations is taken
and written down as shown in Table 1, number N being chosen so that
the time of
transmission of N binary digits should be sufficiently long compared
to the aver
age duration of fading. Transmitting Table 1, not by columns, but by
horizontal
lines, a part of the transmitted signal will vanish owing to fading.
Replacing
the vanished digits by an asterisk, we obtain Table 2 for the
received signal. Yl
If the received d1gits are now grouped according to columns, we
obtain code com
binations from which certain individual digits have vanished. If N 
and this is
the essential point  was chosen in conformity with the statistics of
fading, the
disappearance of an individual digit from the combination can be
considered as
Card 1/ 5
Antifading coding
24846 S/106/60/000/004/001/007
A055/A133
an independent event. The digits that vanished owing to fading are
distributed
in a random manner in code combinations. If each column contains one
combination,
the errors An the same positions in the adjacent combinations are
strongly corre
lated. But if several combinations, representing a certain section
of the com
munication, are placed in one column, the error can already be
considered as in
dependent, not only within the given combination, 'out also within
the limits of
the communication section. In the case of an additive interference,
a certain
digit is replaced by an erroneous one (e.g. 0 by I or vice versa).
In the case
of a multiplicative interference of the fading type, the digit,
isnot replaced,
but vanishes altogether. If not more than r vanished digits must be
restnred, it
is sufficient to use the code with a distance between combinations
at least equal
to r + 1. Comparing the received combination with all possible ones,
it can be
seen that the received combination coincides with the transmitted
one and differs
from all other combinations in at least one digit. The transmitted
combination
can thus be identified ando consiquently, all the vanished digits
can be restored.
If the same. code is used in the presence of an additive
interference, it will
merely allow to detect errors whose number does not exceed r; it
will not'allow
to locate them, and their correction will thus be impossible. The
interference
killing feature is characterized by the probability of an errorfree
reception of

Studied the exchange reactions between accelerators contg S and
the chemically.bound or
sulfur of rubber using radioactive isotope 835. Results indicate
that under
the conditions of tech vulcanizatiot of rubber, it is free S and
not the S bound to the
ru'bber that engages In exchange reactions with the S atoms of the
accelerator. Presented
