Abstract: An active-set PAR reduction method has low computation cost and delay. Peak canceling, by adding up the original signal and the peak canceling signal, is done only after the final peak canceling signal that can reduce all peaks of the resultant signal below the desired peak level is generated with an iterative method or a maximum iteration is reached. The PAR reduction method cancels the high computation cost for accumulating the peak-canceling effort into each sample every iteration. In the i -th iteration, the method attempts to resolve an intermediate peak canceling signal that can reduce the i peaks of the resultant signal to the desired peak level. The method only calculates the samples of the intermediate peak canceling signal and performs balance testing in some locations where the peak level of the original signal is larger than a selected threshold.
