Abstract:
1. A method comprising: receiving multiple input multiple output (MIMO) radio frequency (RF) signals through M antennas coupled via N beamformers to a MIMO receiving system having N channels, wherein M>N; measuring channel fading rate at a baseband level; grading each one of K antennas, based on their total data throughput coming from various data streams, wherein the total data throughput is represented by a total data throughput indicator (TDTI); determining a number of antennas L to be combined out of the K antennas of each one of the N beamformers, based on the measured fading rate, wherein the selecting of said specific subset L is based on the total data throughput grades of the K antennas; and repeatedly applying a tuning process to L antennas at each of the N beamformers, wherein the tuning process comprises adjusting a phase of each of said L antennas to maximize a TDTI.
