Abstract

We propose a time reversal and minimum inter-symbol interference (TR-MISI) serial prefilter for indoor wireless communication system. Proposed TR-MISI serial prefilter minimizes inter-symbol interference (ISI) and makes received peak power be robust to noise. Since the TR prefilter does not minimize the ISI and the joint zero-forcing and TR prefilter does not guarantee the performance in low signal-to-noise ratio (SNR) environment, we consider these two facts in designing an optimization problem for proposed TR-MISI serial prefilter. We use the semidefinite relaxation to solve the optimization problem and get a near-optimal solution. The simulation results show that proposed TR-MISI serial prefilter improves the bit error rate performance at overall SNR.
