The method of channel estimation generates an initial channel estimate from a pilot signal in a received signal, and estimates the data in the received signal using the channel estimate. An updated channel estimate is then obtained from the estimated data. This process of estimating the data and re-estimating...http://www.google.ca/patents/US6614857?utm_source=gb-gplus-sharePatent US6614857 - Iterative channel estimation and compensation based thereon
