The present application discloses a signal processing method, apparatus and system, which relates to the field of communication. The method includes: compressing the input signal bit width at the compression end to obtain the first quantization noise and the compressed signal; compressing the first quantization noise at the compression end to obtain the second quantization noise, the spatial direction of the second quantization noise and the spatial direction phase of the effective signal in the compressed signal. Similarly, the compressor transmits the compressed signal and the second quantization noise to the decompressor, and the data frame is used to instruct the decompressor to cancel the intra-beam noise in the compressed signal by using the second quantization noise obtained from the decompression to get the output signal. The application can ensure that the output signal recovered by the decompressor according to the second quantization noise and the compressed signal is not distorted, and improve the quality of the output signal; moreover, the total data amount of the second quantization noise and the compressed signal is small, thus reducing the data flow transmitted by CPRI.
