The invention provides a communication signal detection method/system, a computer readable storage medium, and equipment. The method comprises the steps: carrying out the self-correlation of an initial communication signal, so as to correct the communication signal; extracting a pilot frequency symbol of the communication signal, and estimating a first channel response parameter and a first channel response matrix of the communication signal according to the pilot frequency symbol and a local pilot frequency sequence; equalizing the communication signal according to the first channel responsematrix, and carrying out the hard discrimination of the equalized communication signal, so as to form a reconstruction signal; estimating a second channel response parameter and a second channel response matrix of the reconstruction signal, and carrying out the fitting of the second channel response matrix, so as to obtain a third channel response matrix; equalizing the communication signal according to the third channel response matrix; comparing the re-equalized communication signal with a reference signal of the communication signal, and detecting the waveform error between the two sides. According to the invention, the method completes the synchronization, effectively reduces the impact from attenuation and noise, and is good in algorithm peformances.
