Abstract:

In this paper, we present a new channel estimator design of a receiver for the next generation high-speed mobile data communications based on OFDM. First an overview of the OFDM system suitable for mobile communications is described. The effects of non-ideal transmission conditions of the OFDM system including channel estimation errors, symbol timing offset, carrier and sampling clock offset, phase noise and time selective fading are analyzed. We then propose a new channel estimator design of receiver in which all of these issues relevant to the mobile transmission environment are addressed. Novel techniques for symbol timing and frequency synchronization are proposed. The architecture of the new subband channel estimator and resulting implementation complexity are then analyzed. The overall performance of the proposed receiver is simulated and evaluated in various channel conditions.
