Viterbi decoder for wireline modems |
摘要 |
A Viterbi decoder is disclosed particularly suited for implementation in a microprocessor-based modem. The decoder calculates the branch metric corresponding to each point of a signal constellation by calculating the Euclidean distance between a received point and a subset of constellation points. Prior to the metric calculations, each received point is translated to the first quadrant and, if necessary, truncated.
