Soft decision analyzer and method

摘要

A soft decision analyzer system is operable to interconnect soft decision communication equipment and analyze the operation thereof to detect symbol wise alignment between a test data stream and a reference data stream in a variety of operating conditions.

主权项

1. A system to analyze a soft decision of a communication system comprising at least one of a data source, a transmitter, a receiver, and a baseband signal processor, comprising:
a scaling module built into programmable hardware operable for receiving a reference data stream from said data source and a test data stream from said receiver, whereby said test data stream and said reference data stream each is assigned a numerical value based on a polarity and each bit of said test data stream is assigned a value indicative of the level of confidence in the soft decision; and a correlator bank built into said programmable hardware operable to analyze symbol wise alignment of said reference data stream against said test data stream, said correlator bank being configured to produce a correlator signal dependent on said symbol wise alignment.
