Patent ID: 8750210

Claim:
A radio for wireless communication, the radio comprising: a plurality of radio output ports; a plurality of power amplifiers; power pooling circuitry, the power pooling circuitry: adjusting, by a digital matrix, gains and phases of a plurality of carrier signals based on first feedback signals such that outputs of the plurality of power amplifiers add coherently only at N selected ones of the plurality of radio output ports, N being an integer less than all of the plurality of radio output ports, and destructively interfere at remaining radio output ports; and selectively directing-output signals from the power amplifiers to N selected ones of the plurality of radio output ports, 1/N of a total output of all the power amplifiers being allocated to each of the N selected radio output ports, N being less than a total number of the plurality of radio output ports, the first feedback signals being based on the output signals; and a plurality of digital direct up-converters, each of the plurality of digital direct up-converters in communication with a corresponding power amplifier, each of the plurality of digital direct up-converters processing the adjusted carrier signals, the processing including up-sampling the adjusted carrier signals; and the plurality of power amplifiers amplifying the adjusted up-sampled carrier signals and outputting the amplified adjusted up-sampled carrier signals for transmission using the selected N radio output ports.
