Abstract

The invention discloses a signal processing method and system. The method includes: calling a preset extraction value, and determining the filtering point of an input signal according to the extraction value; filtering the input signal according to the filtering point to obtain a filtering signal ; Use the filtered signal as the final output signal. Therefore, compared with the filtering operation in the prior art, the method provided in the embodiment of the present invention can avoid some invalid operations, thereby reducing the calculation amount of the filtering operation and improving the processing performance of channelization.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a signal processing method and system. Background technique [0002] Channelization technology is used to extract single or multiple independent sub-band signals within the receiving bandwidth to facilitate back-end baseband processing. The channelized products implemented by software have structural reconfiguration and flexibility. [0003] According to the number of extracted sub-band signals, the channelization technology can be simply divided into single-channel channelization technology and multi-channel channelization technology. [0004] Single-channel channelization technology is to extract only a single sub-band signal. A common implementation method thereof is based on a digital down conversion (English: Digital Down Conversion, DDC for short) channelization technology. According to the bandwidth of the extracted sub-band signal, this type of t...
