Title:
SIGNAL PROCESSING METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/098706
Kind Code:
A1
Abstract:
The present application discloses a signal processing method, device, and system, which relate to the field of communications. The method comprises: a compression end performing bit-width compression on an input signal to obtain a first quantization noise and a compressed signal; the compression end compressing the first quantization noise to obtain second quantization noise, a spatial direction of the second quantization noise being the same as that of a valid signal in the compressed signal; the compression end forming a data frame from the compressed signal and the second quantization noise and sending the data frame to a decompression end, the data frame being used to instruct the decompression end to use the second quantization noise obtained by de-framing to cancel in-beam noise in the compressed signal to obtain an output signal. The present application can ensure that an output signal recovered by the decompression end according to the second quantization noise and the compressed signal is not distorted and the quality of the output signal is improved. In addition, a total data volume of the second quantization noise and the compressed signal is small, thereby reducing data traffic transmitted by a CPRI.
