The invention is applicable to the technical field of broadband digital communication, and relates to a quick search method for optimal time domain candidate signals of a partial transmission sequence algorithm, which comprises the following steps of: firstly, calculating a small amount of time domain candidate signals, generating a peak threshold C based on the small amount of time domain candidate signals, and then, in the calculation process of the residual time domain candidate signals, calculating the optimal time domain candidate signals according to the peak threshold C; judgment is made through calculation of local element numerical values of a small proportion of signals and threshold comparison, and whether the numerical values of the remaining elements need to be calculated continuously or not is judged accordingly. According to the method, under the condition that the peak-to-average ratio reduction performance which is the same as that of an exhaustion search scheme is obtained, the time domain c
