Adaptive reference symbol method and apparatus for a receiver

摘要

A method uses a set of reference symbols. The method includes receiving a first symbol, comparing the first symbol to the set of reference symbols, and selecting a reference symbol from the set of possible reference symbols. The set of reference symbols are adjusted by a set of respective error factors for each of the reference symbols. The reference symbol is selected when it matches the first symbol. The method also includes adjusting the respective error factor for the reference symbol in accordance with a difference between the first symbol and a remodulated reference symbol in one embodiment.

1. A method of using a set of reference symbols, comprises:
receiving a first symbol; comparing the first symbol to the set of reference symbols; selecting a selected reference symbol from the set of reference symbols, wherein the selected reference symbol is selected in response to the selected reference symbol matching the first symbol; and adjusting a respective error factor for the selected reference symbol in accordance with a difference between the first symbol and the selected reference symbol, wherein the set of reference symbols are adjusted by a set of respective error factors corresponding to the set of reference symbols, wherein the selected reference symbol is stored and the adjusting uses the selected reference symbol and a phase rotator, the phase rotator applying a respective error factor of the respective error factors to the selected reference symbol.
