Abstract :
In this paper we extend the analysis of the performance of the APSK modulation, often limited to the AWGN channel, by considering its application in wireless tactical scenarios for land mobile systems. First, the implications of reduced PAPR on the total degradation are explored, taking into account the non-linear effects due to HPAs and the need to use adaptive pre-distortion. Then, the bit error rate performance is assessed by simulation, for some typical multipath scenarios with decision feedback equalization, also including the presence of turbo channel coding.
