Abstract:
1. A multi-antenna wireless diversity receiver comprising: a first receive path having a first amplifier and a first frequency downconverter, operable to receive, amplify, and frequency downconvert a first multipath of a desired signal to provide a first baseband signal, the first receive path having circuit blocks using high power for high system performance; and a second receive path having a second amplifier and a second frequency downconverter, operable to receive, amplify, and frequency downconvert a second multipath of the desired signal to provide a second baseband signal, the second receive path implemented with circuit blocks that inherently consume less power than the circuit blocks of the first receive path, the first and second receive paths are interdependently alternatively enabled based directly on a detected presence of jammer signals out-of-band and independently associated with at least one of the first multipath signal and the second multipath signal.
