System Considerations of M-Ary PSK Land Mobile Radio for Efficient Spectrum Utilization
Summary :
Spectrum efficiency of M-ary PSK land mobile radio is discussed theoretically, where the efficiency ηT (erl/Hz-m2) is defined as the spatial traffic density per system bandwidth. Effective techniques to increase ηT are reviewed. Effects of multi-level modulation, diversity reception, forward error correction (FEC) and detection scheme upon ηT are clarified. It is shown that the combination of quadri-phase-shift-keying with coherent detection (QCPSK) and the FEC at a certain coding rate makes ηT maximum. For the optimum system, ηT and the system capacity are evaluated under a practical condition.
