Channel Estimation for Transmitter Diversity OFDM Systems

Abstract

Orthogonal frequency division multiplexing (OFDM) technique has been applied broadly in the transmission of high speed data in wireless communication. Transmitter diversity can be used with OFDM systems for performance improvement in a fading environment. In this paper, we investigate transmitter diversity for OFDM systems in high speed wireless data applications, and propose a low complexity channel estimation approach for transmitter diversity OFDM systems
