摘要:
A feedforward receiver and method are described herein that address inter-symbol interference in received symbols by using an enhanced equalizer to generate joint soft values (joint information of a previous modem bit x′ and a modem bit x) and an enhanced decoder which uses the joint soft values and side information (bias about the previous modem bit x′) to output a more reliable information bit x.
