IMPLEMENTING BLIND TUNING IN HYBRID MIMO RF BEAMFORMING SYSTEMS |
摘要 |
A system and a method for applying a blind tuning process to M antennas coupled via N beamformers to a multiple input multiple output (MIMO) receiving system having N channels, wherein M>N, are provided herein. The method includes the following steps: Periodically measuring channel fading rate at a baseband level to determine the number of antennas L out of K antennas connected to each one of the beamformers, to be combined at each one of the N beamformers; assigning the antennas to the subset L according to some criteria such as best quality indicator; repeatedly applying a tuning process to L antennas in each one of the N beamformers. |

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; determining a number of antennas L to be combined out of K antennas of each one of the N beamformers, based on the measured fading rate; and repeatedly applying a tuning process to L antennas at each of the N beamformers. |
