摘要

In this paper, the authors survey the system degradation due to mobility and propose a new technique to combat the effects of Doppler spread in Digital Video Broadcasting Satellite to Handheld (DVB-SH) receivers. This paper proposes a very low complexity Intercarrier Interference (ICI) cancellation scheme that performs as other existing methods, while reducing significantly the hardware resources consumption. The proposed method is based on implementing a reduced version of the leakage matrix, that models the ICI in a mobile channel. Simulation results show a gain in the carrier to noise ratio C/N up to 9 dB for a bit error rate BER = 10~(-5) when compared to a DVB-SH receiver with no ICI compensation. In terms of receiver speed, simulations show an improvement up to 50 % in the best case.
