Abstract

A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. In at least one embodiment of the present invention, a control strategy may be employed to regulate the quality level of a signal delivered by a codec in order to balance the performance realized in the reproduction certain signals with overall communication stability in the wireless communication device. The regulation of signal quality level may be affected by reducing the bit rate of a codec, changing the codec to select another codec with a lower bit rate, or by performing bitrate scaling with the codec signal.
