The method of assessment synchronous frequency-modulating broadcast technical parameter based on PEAQ algorithms

The present invention provides a kind of methods of the assessment synchronous frequency-modulating broadcast technical parameter based on PEAQ algorithms.The present invention is using 1 psychoacoustic models of ITU R BS.1387 to rely on, using measurement standards of the objective evaluation index ODG exported based on PEAQ algorithms as synchronous frequency-modulating broadcast test result.The test model of this synchronous frequency-modulating broadcast system not only allows for the influence that the time variation of the non-linear and noise of fm demodulation system is brought, also so that demodulating the quality of audio closest to the subjective feeling of human ear.Synchronous frequency-modulating broadcast model is using program of radio station as signal source, carrier frequency, percentage modulation delay and field strength this four parameters can be changed in parameter error device, statistical analysis is carried out to substantial amounts of data by computer, provide the correlation curve of the reception audio quality of synchronous frequency-modulating broadcast key parameter, so as to establish the objective standard of a subjective assessment, the design considerations of the technical parameter and website of synchronous frequency-modulating broadcast is drawn.
