Abstract
A novel and useful apparatus for and method of distributed coexistence for mitigating interference in a single chip radio and/or a multi-radio (i.e. multi-transceiver) communications device. The invention enables coexistence 'friendly' radio IPs having frequency agility in that they are capable of shifting their clock frequencies thereby avoiding frequency bands of potential victim radios. Frequency agility on the aggressor radio side (rather than by mitigating the effect of interference on the victim radio side) prevents harmonics from the aggressor's clock scheme from falling in the operating frequency band of the victim radio, and in turn causing degradation to its performance. Each aggressor radio, based on information received from other radios, configures the root clock frequency of its RX and/or TX chain clock generation circuits.
