Abstract
The invention relates to an LMS-based asynchronous receiver for digital transmission and recording systems. The receiver comprises a digital adaptive equalizer (EQ) for receiving a received sequence rn and for delivering an equalized sequence yn. The equalizer (EQ) operates at the sampling rate 1/Ts, asynchronous to the data rate 1/T. An equalizer adaptation method using LMS techniques is described for adapting equalizer taps asynchronously to the data rate via a control loop. A first sampling rate converter (SRC) performs timing recovery at the data rate 1/T after equalization on the equalized sequence yn. A second sampling rate converter (SRC) is provided for converting a delayed version of the received sequence rn into an intermediate control sequence ik at the data rate 1/T.
