Abstract:
1. A method for searching carrier frequencies, comprising: determining all the carrier frequencies to be measured within a frequency band according to a predetermined frequency interval; selecting a part of the carrier frequencies to be measured as sampling measurement carrier frequencies according to a predetermined band search step, and for each of the sampling measurement carrier frequencies, calculating an initial peak to average ratio of the sampling measurement carrier frequencies; weighting the initial peak to average ratio of each of the sampling measurement carrier frequencies by using initial peak to average ratios of sampling measurement carrier frequencies left and right neighboring the each of the sampling measurement carrier frequencies, so as to obtain a determined peak to average ratio of the each of the sampling measurement carrier frequencies; and ordering the determined peak to average ratios of all the sampling measurement carrier frequencies, and selecting, in a descending order of the determined peak to average ratios, a predetermined number of sampling measurement carrier frequencies and frequencies to be measured left and right neighboring the selected sampling measurement carrier frequencies as a search result.
