Low complexity channel estimation for the WB-CDMA terminal

Channel estimation is of crucial importance for tomorrow´s wireless mobile communication systems. However, high-performance algorithms often come at the cost of a high computational complexity, which makes them unsuitable for the terminal equipment. A low-complexity version of an iterative channel estimator is proposed for the 3rd generation WB-CDMA (wideband code division multiple access) terminal. Its performance compares favorably with the ones of the original version. Furthermore, a novel criterion for false-paths detection is introduced, thus avoiding useless computations to be performed later on. Possible improvements are proposed
