Zusammenfassung:Channel estimation is very important for MIMO (Multiple Input Multiple Output) OFDM (Orthogonal Frequency Division Multiplexing) systems, while computation required is relatively large. Block-pattern optimal pilot reduces the computation, but is not suitable for high speed mobile environment. In this paper, comb-pattern optimal pilot is proposed to reduce the error of channel estimation. It can be proved by simulation that performance of system with comb-pattern optimal pilot is much better than that with block-pattern optimal pilot, and the computation required is still small.
