摘要
A method and apparatus for decision-directed adaptation for coded modulation is presented in which a modulation decoder and data re-encoder are used to create an estimated version of a received signal based on the use of a reliable modulation code. An adaptive equalizer is used to process the received signal, and the differences between the received signal passed through the adaptive equalizer and the estimated version are used by the adaptive equalizer to set the equalizer coefficients. A variety of adaptation algorithms can be used including Least Mean Squares (LMS) and Recursive Least Squares (RLS).
