摘要：
In this paper, the current analysis focuses on the influence of demodulation performance in multipath fading propagation environments, which results from the pilot power variation of pilot symbol assisted modulation (PSAM) M-PSK in orthogonal frequency division multiplexing (OFDM) systems. The pilot-to-data power ratio (PDR) is optimized analytically. Theoretical and simulation results show that the optimum PDR is effected by the signal-to-noise ratio (SNR), Doppler frequency and interpolation size etc, and provide a suitable tool for system design(1).
