The authors propose a new blind space-time minimum variance (MV) receiver with a built-in channel parameter estimation algorithm for asynchronous code division multiple access (CDMA) systems. According to the simulation study, the proposed algorithm demonstrates accurate channel estimation capability and shows superior performance to conventional or single antenna MV receivers.
