The frequency and symbol rate offset compensating algorithm for simultaneous estimation of echo and channel responses

This paper addresses two critical problems in designing the new full-duplex fast training algorithm for simultaneously estimating echo and channel responses. Although algorithms of this type have been discussed and evaluated in our previous publication, the proposed algorithm concentrates on the following two problems that were not solved in the previous approaches: (1) the symbol rate difference between the local transmitter and the remote transmitter, and (2) the frequency offsets in both far echo and far signal that are caused by the analog carrier network. The performance of the new method is analyzed in terms of mean-square error. Simulation results are presented to confirm the analysis
