Abstract:
A phased array receiver for use with a first received analog signal and a second received analog signal, the phased array receiver including: a first analog to digital converter to generate a first received digital signal; a second analog to digital converter to generate a second received digital signal; a first down-sampler to generate a first down-sampled digital signal; a second down-sampler to generate a second down-sampled digital signal; a first polyphase low pass filter to generate a first filtered down-sampled received digital signal; a second polyphase low pass filter to generate a second filtered down-sampled received digital signal; and a beamforming core to generate a beamformed signal, wherein the first received signal is related to the first filtered down-sampled received digital signal, and wherein the second received signal is related to the second filtered down-sampled received digital signal.
