F-QPSK-A superior modulation for future generations of high-capacity microcellular PCS systems

@inproceedings{citeulike:2713258, abstract = {A coherent F-QPSK modem radio technique is proposed for future generations of high-capacity personal communication services (PCSs) systems. F-QPSK is a constant envelope modulation that is 6 to 8 dB more power efficient than non-constant envelope signalings like the \π/4 DQPSK as used in the US IS-54 digital cellular mobile radio and the Japanese Handyphone standards. A comprehensive evaluation of F-QPSK's adjacent channel interference (ACI) characteristics, spectral efficiency in b/s/Hz/m² and bit error rate (BER) performance in a PCS cellular environment is presented.
