Enhancement of Coexistence Performance in a DRP Based Multi-Radio Environment of a Mobile Phone

The incorporation of Bluetooth and Wireless LAN transceivers in a mobile device poses design challenges associated with their coexistence with the cellular transceiver, as they often need to operate concurrently and their close proximity is inevitable. We present recently developed techniques that transform the RF and analog circuit design complexities, typically encountered when targeting coexistence performance improvements, into the digital domain, and demonstrate how these techniques allow the concurrent operation of multiple transceivers without one adversely impacting the performance of the other. The ideas presented have been implemented in Bluetooth/WLAN transceivers offered by Texas Instruments.
