Abstract
A method and apparatus for selecting a preferred signal from homogenous streams of a subscriber call in an analog or mixed mode wireless communication network. The method and apparatus have particular significance to un-decoded analog radio packets which require digital signal processing to decode at least their signaling information. The method allocates at least one stream with the best signal qualities to real-time full-decoding in a DSP, and allocates lower quality streams to non-real time burst decoding in the same or another DSP. As signaling quality changes in the homogenous streams, the full-decoding can be re-allocated to a now higher quality stream. Burst decoding lower quality streams allows for more efficient use of DSP processing power and allows more streams to be processed without significant affect on audio content or quality.
