Claim of US Patent No. 10,716,111

1. A backhaul radio comprising:a plurality of receive radio frequency (RF) chains, wherein each receive RF chain is capable of converting from one of a plurality of receive RF signals to a respective one of a plurality of receive chain output signals;
a plurality of directive gain antenna elements; and
a processor at the receiver to compute and feedback the phase and sample timing offset (STO) for optimal beamforming,
wherein the processor is further configured to calculate a plurality of relative STOs and a plurality of relative phase offsets and average and quantize the plurality of relative STOS and the plurality of relative phase offsets to determine the feedback.
