摘要：This paper presents a study on the Design of high performance turbo encoder and iterative turbo decoder using different algorithms. In data transmission, turbo coding helps achieve near Shannon limit performance. MAP, LOG-MAP and SOVA Algorithms have been studied and their design considerations have been presented. Turbo coding is an advanced error correction technique widely used in the communications industry. Turbo encoders and decoders are key elements in today’s communication systems to achieve the best possible data reception with the fewest possible errors. The basis of turbo coding is to introduce redundancy in the data to be transmitted through a channel. The redundant data helps to recover original data from the received data. The design problem of generating the turbo code and decoding the code iteratively using MAP detectors has been considered. This paper has proposed a design of a TURBO Decoder using MAP Algorithm.
