Channel detector implementation with postcoder

摘要

A signal detector/decoder is implemented in multiple stages. The beginning stage is configured to input channel data bits and to output hard data bits based on the channel bits and a maximum likelihood (ML) path. The next stage includes a postcoder coupled to receive channel domain information from the first stage and to convert the channel domain information to user domain information. The final stage includes a reliability unit coupled to receive the user domain information from the postcoder and to output user domain soft information for the hard data bits based on the ML path estimation and the user domain information.

1. A signal detector, comprising:
a first stage configured to input channel data bits and to output hard data bits based on the channel data bits and a maximum likelihood (ML) path; a second stage comprising a postcoder coupled to receive channel domain information from the first stage and to convert the channel domain information to user domain information; and a third stage comprising a reliability unit coupled to receive the user domain information from the postcoder and to output user domain soft information for the hard data bits based on the ML path estimation and the user domain information.
