Abstract
A new class of differential detection techniques for standardized Feher patented quadrature phase-shift keying (FQPSK) systems is proposed and studied by computer aided design/simulations. It is shown that significant BER performance improvements can be obtained by increasing the received signal’s observation time over multi-symbol as well as by adopting trellis-demodulation. While the FQPSK transmitted signal is not trellis coded, its trellis coded interpretation leads to trellis demodulation. For example, our simulation results show that a BER=10-4 can be obtained for an Eb/N0=14.1 dB.
