Abstract
A communications system and method for transmitting digital
information includes arranging a modulator to have an
input bit stream of binary data and arranging a signal generator
to generate four orthonormal hyper phase shift keying
(HPSK) basis functions that are periodic functions with a
duration T. A bit to symbol mapper is arranged to combine the
bit stream and the HPSK basis functions to form a succession
of 4-bit HPSK symbols for 16-HPSK, 5-bit HPSK symbols
for 32-HPSK or 6-bit HPSK symbols for 64-HPSK, and a
transmitter is arranged to transmit signals indicative of the
HPSK symbols. A receiver is arranged to receive the signals
from the transmitter and the HPSK symbols are demodulated
with the HPSK basis functions to reproduce the bit stream of
binary data.
