Title: Method and apparatus for power control in a transmitter

Abstract: A processor (120) receives an input signal including symbols for transmission, and determines an output signal for a symbol period from a predetermined range of symbols of the input signal in combination with a modulating phasor vector and a matrix of filter coefficients. The processor compares samples of the output signal with a predetermined amplitude limit; and, in response to a sample of the output signal exceeding the predetermined amplitude limit, adjusts the symbols of the predetermined range of symbols that are not pilot symbols by an adjustment factor, thereby creating a new input signal. If a sample of the output signal exceeds the predetermined amplitude limit, the processor computes a new output signal from the new input signal in combination with the modulating phasor vector and the matrix of filter coefficients; and generates a power-controlled modulated radio signal from the new output signal.
