Systems and methods for maintaining operation of a receiver co-located with a transmitter and susceptible to interference therefrom by desensitization of the receiver

The present invention relates generally to the field of communication, and, more particularly, to communication devices having a co-located transmitter and receiver in which the transmitter can interfere with the operation of the receiver. Systems and methods can be used to maintain operation of a receiver co-located with a transmitter in a communication device and susceptible to interference therefrom by anticipating the intervals during which the transmitter is active (i.e., transmitting) and then desensitizing the receiver during that interval. Although the receiver may operate in a reduced capacity due to periodic desensitization, the adverse effects of interference generated by the transmitter can be avoided. For example, interference from the transmitter can cause variables, such as the gain applied by an automatic gain control module at the receiver input, to deviate from a normal operating or steady state value, which must then be recovered when the interference from the transmitter ceases.
