|Abstract:||Blind channel estimation for cyclic prefixed single-carrier (CP-SC) systems via second order statistics (SOS) is considered in this paper. By fixing one or more symbols in the transmitted block to be real, we develop a simple technique for blind channel estimation that does not need redundant precoding or virtual carriers. A side-benefit, yet a novel contribution of the proposed algorithm, is that the phase ambiguity, an inherent problem in traditional blind channel estimation, is also resolved. The elimination of phase ambiguity facilitates signal detection for digital communications where symbols are usually taken from the finite alphabet. The results of the computer simulations clearly show the effectiveness of our proposed algorithm. ©2006 IEEE.|
