A method of performing interference cancellation (IC) in a wireless communication device having a receiver comprising at least a primary receiver chain and a diversity receiver chain includes determining an interference level of a transmitted signal on the receiver; determining whether the interference level is within a predetermined range; selecting a first mode of operation if the interference level is within a predetermined range; and selecting a second mode of operation if the interference level is not within the predetermined range. The first mode includes receiving, at the primary receiver chain, a first signal corresponding to the transmitted signal; receiving, at the diversity receiver chain, a second signal corresponding to the transmitted signal for providing to an IC circuit; generating, at the IC circuit, an output signal based on the second signal; and generating a cancellation signal based on the output signal and the first signal. |

1. A method of performing interference cancellation (IC) in a wireless communication device having a receiver comprising at least a primary receiver chain and a diversity receiver chain, the method comprising:
determining an interference level of a transmitted signal on the receiver; determining whether the interference level is within a predetermined range; selecting a first mode of operation if the interference level is within a predetermined range; and selecting a second mode of operation if the interference level is not within the predetermined range; wherein the first mode comprises:
receiving, at the primary receiver chain, a first signal corresponding to the transmitted signal;receiving, at the diversity receiver chain, a second signal corresponding to the transmitted signal for providing to an IC circuit;generating, at the IC circuit, an output signal based on the second signal; andgenerating a cancellation signal based on the output signal and the first signal; wherein the second mode comprises:
receiving, at the primary receiver chain, a first signal corresponding to the transmitted signal;processing, via the primary receiver chain, the first signal;receiving, at the diversity receiver chain, a second signal corresponding to the transmitted signal; andprocessing, via the diversity receiver chain, the second signal. |
