Design and Implementation of Low-Rate Turbo Coding and Decoding

Turbo coding, with its performance closely approaching the Shannon limit, is an excellent modern error-correcting coding. In recent years, the 6th generation (6G) mobile communication has put forward higher requirements for the coding rate range and Bit Error Ratio (BER) performance. To meet these requirements, a low-rate Turbo encoding and decoding scheme has been designed and implemented. By puncturing, the designed scheme supports a wide range of coding rates (i.e., 1/9 to 1). The feasibility and effectiveness of the designed scheme have been verified through the BER performance simulations and Field Programmable Gate Array (FPGA) implementation.
