Abstract
Systems and methods for antenna selection in a wireless terminal with two radios are provided. Signals received using first and second antennas are demodulated by first and second modems according to first and second protocols. A receive path between the second antenna and the second modem can be controlled to receive signals according to the first protocol. A performance measure of demodulating, according to the first protocol, a signal received using the second antenna is determined. The performance measure may be determined using a mirror module in the second modem or using a search module in the first modem. The wireless terminal switches antennas so that the first modem demodulates a signal received using the second antenna, if the performance measure for using the second antenna is such that the switch would improve performance of the first modem.
