ABSTRACT:
A method for increase receiver efficiency in a multimode communication device includes a first step of monitoring a received signal strength of a neighboring cell on a receiver channel. A next step includes determining a noise on the receiver channel from a transmitter power amplifier of the communication device. A next step includes comparing the level of interference with a predetermined threshold and with respect to the signal strength. A next step includes blanking the receiver when the transmitter power amplifier of the communication device is on and if the predetermined threshold is not exceeded indicating excessive self-interference.
