Abstract: A method of spatial modulation using an antenna array including radiating elements having power amplifiers communicatively coupled thereto. An amplitude of an output signal to be formed in space is determined by the antenna array based on an input signal. Output amplitude levels for the radiating elements are determined based on the amplitude of the output signal and a current output amplitude level of the antenna array. The first signal(s) for a first subarray of the antenna array and the second signal(s) for a second subarray of the antenna array are generated based on the input signal. The output amplitude levels are assigned to the power amplifiers of the radiating elements. The first signal(s) are sent to radiating elements of the first subarray and the second signal(s) are sent to radiating elements of the second subarray for transmission therefrom to form a combined signal in space as the output signal.
