Abstract

A novel channel estimation scheme based on superimposed training is proposed for space time block coded (STBCO) multi-band (MB) orthogonal frequency division multiplexing (OFDM) ultra-wideband (UWB) systems. The optimal training symbols are derived with respect to the least square (LS) channel estimate mean square error (MSE). Simulation shows that the proposed scheme benefits much higher effective data throughput over the conventional method.
