Research And Design Of Channel Coding And Multiplexing Of TD-SCDMA Radio Interface Physical Layer

Work of this paper focus on the core technology , namely Channel Coding and Multiplexing of baseband signal process of radio interface physical layer in TD-SCDMA. Algorithm and realization of software and hardware about key modules are initially researched and designed.These modules comprise CRC verification module,channel coding and decoding module, composed of convolution codec and turbo codec,interleaving module and rate matching module. Software and hardware design of CRC verification module and channel coding and decoding module are amphasizely finished,and the algorithm and software design of interleaving module and rate matching module are realized.Verilog HDL was used to program,and software and hardware simulation are completed.Research and design of this paper establish a generally whole frame for our lab to fullly study on channel coding and multiplexing of TD-SCDMA.Key modules are divided and software and hardware realization of these modules are finished in various degrees.Such as convolution codec of channel coding and decoding module is synthesized to gate-level circuits and is accomplished simulation. Software design and algorithm of other key modules are completed too.All these work bring some exerpiences for future further study and other designs in digital communication fields.Also,making technical accumulation for future study of our lab.
