Adaptive diversity receiver architecture

摘要

A diversity receiver circuit that adaptively selects a variable number of one or more antennas for use in improving signal quality. Each antenna is provided its own receiver that each generates a representation of a received signal. This adaptive selection offers high dynamic adaptability in using the appropriate antennas and receivers at the appropriate time to thereby improving signal-to-noise ratio. The receivers may be direct conversion receivers that implement up-conversion of the baseband signal to reduce DC offset and 1/f noise characteristic of direct conversion architectures.
