Channel quality estimation for MLSE receiver

摘要

A receive signal processor jointly detects a signal-of-interest with one or more other signals. The signal-to-interference-plus-noise ratio for the signal-of-interest is determined by computing per-subcarrier signal-to-interference-plus-noise ratios for a plurality of subcarriers carrying the signal-of-interest, computing per-subcarrier capacities for the subcarriers based on the per subcarrier signal to interference ratios, and computing a total signal-to-interference-plus-noise ratio for the subcarriers based on the per-subcarrier capacities of the subcarriers.
