Channel Estimation in Mobile Wireless Communication

Channel estimation is an important technical issue in mobile communication system, the performance and capacity of mobile communication system are directly influenced by the speed and precision of channel estimation. This paper introduced the definition and the method currently existed of channel estimation firstly, and then proposed a method based on the probability of gain difference by the feature analysis of mobile wireless fading channel. This method has the virtue of high speed, low complexity and strong real time character to environment.
