ABSTRACT:
A system and method for carrier recovery includes a plurality of carrier recovery modules, each processing the same input symbols, and each having a gain input and an error output. A loop gain control receives errors from the carrier recovery modules and provides gains to the carrier recovery modules. Based upon the errors during a current period, the loop gain control determines which module produced lowest errors, and selects the gain associated with that module as a best gain which is applied to a module which outputs symbols for decoding during a next period.
