Sarpreet Singh · 2013
The turbo encoder is employed to increase the free distance of the turbo code, hence improving its error-correction performance. A Design of Turbo encoder and decoder. In data transmission, turbo coding helps achieve near Shannon limit performance. 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 SOVA detectors has been considered. This paper has proposed a design of a TURBO Decoder using SOVA Algorithm.
