Bandwidth Efficient Differentially Encoded 16 Amplitude Phase Shift Keying (16DAPSK) Schemes for Rician Fading Channels

This study investigates the Bit Error Rate (BER) performance of 16DAPSK and differentially coherent demodulation in presence of AWGN, frequency flat and Rician fading channels via Monte Carlo simulation. The BER performance is also compared with 8DPSK and 16 DPSK. The results showed a large degradation system performance over Rician fading compared with Additive white Gaussian channel, this is due to the increase of the Doppler rate from 0.01 to 0.1 Hz.
