Summary :

In this article, we present a scattered pilot aided channel estimation and tracking technique for MIMO-OFDM systems. First we extend Li's estimation algorithm to scattered pilot-aided case. Then a scattered pilot-aided tracking scheme is developed to track the time-varying MIMO channel. The algorithms we present reduce the system overhead and channel estimation complexity to a low level with acceptable performance degradation. Simulations of a MIMO-OFDM system with four-transmit and four-receive antennas show that the new algorithm has better performance than Li's algorithm in time-varying MIMO channels.
