Abstract

Study on the blind equalization of time reversal based space-time block coding (STBC). Utilizing the constant modulus property of the transmitted signal and exploiting the statistics of property the coding scheme, an adaptive blind equalization algorithm with constant modulus algorithm (CMA) is proposed. Simulation results indicate that the ST-CMA equalizer using Space-Time Coding is able to achieve better performance than a CMA equalizer without using this Space-Time Coding scheme.
