Abstract

In a wireless mobile communication, it is required to provide high-speed and high-quality communication services and orthogonal frequency division multiplexing (OFDM) due to a high bandwidth efficiency and resistance to multipath ability, etc., in recent years, widespread attention. Contents of this paper are the OFDM channel estimation and equalization. Paper introduces the principle and performance characteristics of OFDM, on the basis of in-depth discussion of the principles and methods for channel equalization OFDM systems. The paper discusses the various channel estimation method using pilot signals, and in the traditional pilot minimum mean square error estimation algorithm based on an adaptive MMSE estimation algorithm applied to multi-path channel. It is the tap coefficients multipath channel with KL series expansion, which can automatically estimate these unrelated series coefficients [1].
