Method and system for minimizing effects of transmitter impairments in multiple input multiple output (mimo) beamforming communication systems

A method for processing signals in a communication system, the method comprising:

• performing by one or more processors and/or circuits:
• nulling, in a multiple input multiple output (MIMO) communication system, transmitter-induced noise contained in a plurality of received signals at a receiver based on a transmitter error vector magnitude wherein each of said plurality of received signals comprises information contained in a plurality of spatial streams;
• and
• detecting estimated values for said information contained in said plurality of spatial streams based on said nulling.

A method for processing signals in a communication system, the method comprising:

• performing by one or more processors and/or circuits:
• nulling, in a MIMO communication system, transmitter-induced noise by adjusting at least a portion of a plurality of signals transmitted based on a transmitter error vector magnitude;
• and
• transmitting said plurality of signals subsequent to said nulling.

A system for processing signals in a communication system, the system comprising:

• one or more circuits, in a MIMO communication system, that enable computation of an augmented channel estimate matrix based on a channel estimate matrix, a channel noise matrix, and a transmitter error vector magnitude;
• said one or more circuits enable computation of a feedback vector based on said augmented channel estimate matrix;
• and
• said one or more circuits enable nulling of transmitter induced noise by adjusting at least a portion of signal levels for a plurality of input signals based on said feedback vector.
