Abstract:
1. A mobile wireless communication device having a first antenna and a second antenna, comprising: a first bandpass filter operatively coupled to a first low noise amplifier, wherein the first bandpass filter is operatively disposed between the first low noise amplifier and the first antenna; a second bandpass filter operatively coupled to a second low noise amplifier, wherein the second bandpass filter is operatively disposed between the second low noise amplifier and the second antenna; a phase shift adjuster operatively coupled to an RF combiner, wherein the phase shift adjuster is operatively disposed between the RF combiner and the second low noise amplifier, wherein the RF combiner combines a first RF analog signal output by the first low noise amplifier and a second RF analog signal output by the phase shift adjuster; a cluster path processor operatively coupled to the RF combiner, wherein the cluster path processor is configured to track time-wise clusters of multipath signals and to estimate a complex phase and an amplitude of the multipath signals in the signal clusters; and a baseband weight generator that receives information from the cluster path processor and generates a phase control signal to the phase shift adjuster.
