Abstract. The
article deals with the transmission of binary messages. The elements of the
binary message follow with an interval of T0. The binary
message is divided into two threads before transmission. The flow elements are
received for transmission at the same time with an interval of 2T0
and transmitted using the corresponding signals with a duration of T =
4T0. Thus, the signals corresponding to the elements of each
flow partially overlap in time by the value of T/2. The signals corresponding
to the elements of different flows completely overlap in time. The frequency
band occupied by the transmitted signal is 2.36/T. 99% of the signal
power is concentrated in the specified frequency band. The unit cost of the
band 0.59. A variant of element-by-element reception and a variant of reception
of two consecutive elements of the flow, based on the linear independence of
the signals, is proposed. The estimation of transmission noise immunity under
the influence of noise in the form of white noise is made. The considered
method of transmitting a binary message provides a fairly good efficiency
without the use of a spectrum generator.
Key words: overlapping
signals, frequency band, noise immunity.
