According to the abstract released by the Intellectual Property India: "A transmitter signal processor (TSP) for use where multiple independent signals are to be combined, amplified and transmitted whilst maintaining a substantially constant envelope, the processor comprising a feedback network, whereby an error signal between a sum of the signals and an output of a constant envelope process within the TSP is computed, and, for each input signal this error signal correlated with the input signal to model the effect of the error in a receiver, and to produce a feedback signal by multiplying each error signal by its corresponding input signal, and summing the result for each such input signal, and then subtracting the feedback signal from the sum input. The constant envelope process may be all-digital, such as a normalisation process, and/or may comprise a part of the analogue transmit chain, such as amplifiers, frequency convertors or filters."
The patent application was internationally filed on Nov. 07, 2023, under International application No.PCT/EP2023/080925.
