(57) Abstract :
A signal transmission system using single carrier for transmission of signals in one direction comprising first modulator unit at one
end receiving three input signals and said modulator unit consists of a first modulator of continuous phase frequency shift key for
modulating first signal with the input carrier, second modulator of phase shift key for modulating second signal with carrier signal
from output of said first modulator, and third modulator of amplitude shift key for modulating third signal with the carrier of output of
the said second modulator; a communication channel for transmission of the output of the said modulator unit; a second demodulator
unit, at other end receiving input from the said communication channel, consisting of a continuous phase frequency shift key detector
for giving output of transmitted said first signal, a phase shift key detector for giving output of said second signal, and an amplitude
shift key detector for giving said third signal; and for transmission of signal in opposite direction a second demodulator unit, having
features the said first demodulator, in the said one end and a second modulator unit, having features said first modulator unit in the
said other end.
