Abstract :
In this paper, we consider multiple input multiple output Feher-patented quadrature phase shift keying (MIMO-FQPSK) system supporting high spectral efficiency and throughput. Based on the fact that the complex baseband signal sampled at every bit duration has only 8 phase values and its signal can be considered as 8-phase-shift keying (8-PSK) signal, FQPSK demodulation with maximum likelihood sequence estimation (MLSE) is considered and it is extended to MIMO system. The performance of MIMO-FQPSK receiver is analyzed by computer simulation and by considering the union upper bounds for zero forcing (ZF) detection.
