Methods And Apparatus For Reducing The Impact Of RF Interference Based On Estimation Of Colored Noise

摘要

A mobile device having first and second RF transceivers performs a communication function in accordance with a communication protocol of the second RF transceiver. During performance of this function, the mobile device estimates the RF interference on a channel of the first RF transceiver, and stores parameters which characterize the estimated RF interference in association with an identifier corresponding to the function. These actions are repeated for a plurality of channels of the first RF transceiver, as well as for a plurality of different communication functions. When performing a communication function again, the mobile device receives an identifier corresponding to the function and retrieves stored parameters corresponding to the received identifier. The mobile device applies the retrieved parameters to the first RF transceiver for reducing the adverse effect of RF interference during reception on the channel of the first RF transceiver.

1. A method in a mobile communication device for use in reducing the effect of interference of communications using a first radio frequency (RF) transceiver of a first type due to simultaneous communications using a second RF transceiver of a second type, the communication using the first RF transceiver being within a first RF band and the communications using the second RF transceiver being in a second RF band which is adjacent to the first RF band, the method comprising:
performing a communication function in accordance with a communication protocol using the second RF transceiver; estimating an RF interference on a channel of the first RF transceiver during performance of the communication function; storing parameters which characterize the estimated RF interference; when performing the communication function again:
retrieving the stored parameters which characterize the estimated RF interference; andapplying the retrieved parameters to the first RF transceiver for reducing the effect of RF interference during reception on the channel of the first RF transceiver.
