We propose an improved time reversal (TR) prfilter for indoor wireless communication system to maximize signal-to-sidelobe ratio (SSR). Proposed prefilter maximizes peak power of received signal and minimizes inter-symbol interference at the same time by SSR maximization. We design an optimization problem to maximize SSR and find an ϵ-optimal solution. The simulation results show that proposed TR prefilter has better BER performance than the conventional TR prefilter at overall SNR.
