SYSTEM AND METHOD FOR FILTERING SIGNALS IN A TRANSCEIVER

摘要

A system and method for filtering signals in a communications system reduces hardware and chip size requirements by selectively connecting a filter along transmitter and receiver paths of a transceiver. In operation, a controller generated signals for connecting the filter along the transmitter path when the transceiver is in transmitter mode and for connecting the filter along the receiver path when the transmitter is in receiver mode. The controller then generates additional signals for setting one or more parameters of the filter based on the path connected, or put differently based on the operational mode of the transceiver. In a variation, the controller sets the parameters of additional elements coupled to the filter as a way of further controlling processing of the transmitter and receiver signals.
