Title: Channel estimation method of orthogonal frequency division multiplexing relay system
Inventor: XU ZHENG-XIN
IPC: H04J11/00
Filed: 2010-07-08
Abstract: There is provided a channel estimation method of orthogonal frequency division multiplexing relay system, which is applied into a relay system for transmission after amplification. The method is based on an expectation maximization algorithm to estimate, at a destination end, the channel from a source end to a relay system and the channel from the relay system to the destination end. The channel estimation method includes the steps of: establishing a system model, setting an expectation function, performing a maximization processing, and performing iteration. By estimating the channels from the source end to the relay system and from the relay system to the destination end, the present invention allows the signal of the direct path (source end to destination end) and the signal of the relay path (source end to relay system to destination end) to be optimally combined with each other at the destination end.
