ABSTRACT:
A wireless signal processor includes an analog front end for generating at least one baseband analog signal, at least one analog to digital converter for converting the baseband signal into a digital signal, the analog to digital converter having a resolution width and a sampling rate, and a baseband processor for measuring the signal energy in the analog to digital converter output, and when the incoming signal energy level increases or a baseband processor detects a packet, at least one of the sampling rate or resolution width also increases until the end of the packet, after which the sample rate and resolution are reduced to an interpacket rate and resolution. Additionally, the sampling rate and resolution increase after packet detection at rates and resolutions which are dependent on packet type and data rate.
