Abstract:
1. A computer-implemented method for providing power control in a multiple-input and multiple-output (MIMO) communication system, the method comprising the acts of: measuring a plurality of signal strengths provided by a transmitter-side of the MIMO communication system, wherein the transmitter-side comprises a plurality of individual transmitters, wherein the measuring the plurality of signal strengths comprises sampling the plurality of signal strengths a number of times to produce a plurality of signal samples for each of the plurality of transmitters; computing a plurality of standard deviations for each of the plurality of transmitters based on the plurality of signal samples; summing and averaging the plurality of standard deviations to generate a standard deviation average; comparing the standard deviation average to a predetermined tolerance; determining if any of the plurality of transmitters are exceeding the predetermined tolerance based on the comparing; determining if any of the plurality of signal strengths exceeds the predetermined tolerance; adjusting a signal power offset for each of the plurality of individual transmitters corresponding to any of the plurality of signal strengths that exceed the predetermined tolerance; and storing a default signal power offset, based on the adjusting the signal power offset, for use during normal operation of the MIMO communication system.
