摘要：WiMAX IEEE 802.16d is a current trend in the development of high-data-rate wireless systems. Transmit precoding reacts to channel conditions to improve the system capacity or bit error rate (BER). OFDM is being widely adopted in several wireless standards because of its spectrum efficiency and other advantages. Recent integration TH precoding with multiple-antenna techniques promises a significant enhancement in the performance of OFDM system. In this section investigates a new approach to the adaptation of the WIMAX baseband for the physical layer performance of, multi-antenna techniques with TH precoding. THP was devised for equalization of dispersive SISO channels. It is a very efficient approach to remove ISI in single-carrier systems. It enables the application of coded modulation in a without seams fashion and is able to come close to the channel capacity of the underlying channel. Spatial separation in MIMO systems is strongly related to temporal equalization for SISO transmission over ISI channels.
