Abstract

The invention discloses a code rate regulation device with resistance to a burst big error code, and belongs to the technical field of microwave communication. The code rate regulation device with resistance to the burst big error code is implemented on the basis of an FPGA or an ASIC and comprises a multiframe generator, a service mark generator, a frequency mark generator, a sent data buffer, adata multiplexing module, a data demultiplexing module, a frequency controller and a received data buffer. The code rate regulation device with resistance to the burst big error code can be used on achannel encountering a burst big error code case in the wireless microwave communication, reliability and continuity of information transmission can be ensured, and meanwhile, a use range of code rateregulation is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of wireless microwave communication, in particular to a code rate adjustment device for resisting burst large error codes, which can be used on a channel under the condition of burst large error codes. Background technique [0002] Quasi-synchronous data multiplexing modules in communication transmission generally need to adopt code rate adjustment methods. The existing code rate adjustment method is mainly composed of a flag generator, a sending data buffer, a data multiplexing module, a data demultiplexing module, a receiving frequency phase-locked loop, and a receiving data buffer. In this code rate adjustment method, one flag is set for each single frame in the transmission frame structure, and the flag is different for each frame, and the flag is generated by a flag generator. The valid data length and frequency adjustment information are obtained by judging the flag bits at the receiving end. [0003...
