Time Reversal Space-Time Block Coding for FWA Systems

The aim of this paper is to present the application of the time-reversal space-time coding (TR-STBC) on the broadband fixed wireless access (FWA) systems. In addition to the transmit diversity obtained from the TR-STBC scheme, we also consider the concatenation of TR-STBC and an outer channel code in order to provide coding gain for the FWA systems. A turbo equalization scheme is proposed for the concatenated systems. Different receiver strategies are compared, and their performance/complexity tradeoff is discussed.
