Abstract :
Systems designed for high data rate broadband wireless multimedia services must combat fading and multipath impairments. In this paper, the effects of these impairments on transceiver signal processing system design are analyzed, and the system architecture of spatial transmit diversity combined with adaptive modulation is presented. The performance of such a system is compared with conventional single carrier fixed modulation and OFDM systems.
