Abstract:
1. A method of controlling a multiple-input multiple output (MIMO) configuration in a transmitter for a communication system, the transmitter having at least two antennas, at least two amplifiers, a switching network configured for connecting the at least two amplifiers to the at least two antennas, and a configuration processor configured for applying a selected one of at least two configuration matrices to modulated signals to be transmitted before the modulated signals are provided to the at least two amplifiers, each of the at least two configuration matrices corresponding to a respective MIMO configuration, the method comprising: (a) monitoring a parameter that corresponds to a current consumption of the transmitter; (b) determining whether a predetermined condition of the parameter has occurred; and (c) if it is determined that the predetermined condition has occurred, autonomously selecting a MIMO configuration based on the parameter, wherein selecting a MIMO configuration based on the parameter includes determining to reduce the current consumption, applying an antenna-switching matrix to the signals to be transmitted, and configuring the switching network such that matrix-processed signals to be transmitted are directed to one of the at least two amplifiers and one of the at least two antennas.
