Abstract
We present a novel complex decision-aided maximum-likelihood receiver for joint phase noise and frequency offset compensation, with automatic on-line filter weight adaptation using a least-sum-of-squared-error criterion. Frequency offset is acquired quickly and compensated perfectly for a complete frequency offset range of ±1 times the symbol rate.
