Zusammenfassung: | The invention is applicable to the technical field of communications, and provides a parallel carrier recovery method and device, and terminal equipment. The method comprises the following steps of carrying out coordinate transformation on N paths of parallel carrier data to obtain polar coordinate data of the N paths of the parallel carrier data; inputting the polar coordinate data into a phase frequency detector so as to obtain error terms of all the paths of the parallel carrier data; averaging the error terms of all the paths of the parallel carrier data to obtain phase errors of the N paths of the parallel carrier data; and carrying out phase compensation on a phase error input loop filter and a numerical control oscillator, and outputting synchronous carrier data after phase compensation. A frequency deviation and a phase deviation of the parallel carrier data are captured through the phase frequency detector, and the error terms of the multiple paths of the parallel carrier dataare averaged to eliminat |
