✦ Synopsis

Digital data receivers often operate at a fixed sampling rate 1=T s that is asynchronous to the baud rate 1=T. A digital equalizer that processes the incoming signal will also be asynchronous, and its adaptation is commonly based on extensions of the LMS algorithm. In this paper, we develop and analyze a much simpler approach that is based on zero-forcing adaptation techniques. Numerical results for an idealized optical recording channel serve to illustrate the merits of the approach. LMS-like performance is found to be within reach at a fraction of the cost of LMS.
