Turbo Codes
Turbo codes are a class of forward error-correcting codes that achieve extremely low error rates in data transmission over noisy channels. They were first introduced in 1993 by Claude Berrou and Alain Glavieux. Turbo codes are based on the concept of iterative decoding, where the decoding process is performed in multiple iterations. In each iteration, the decoder exchanges information with the other decoder to refine its estimate of the transmitted data. This process continues until a satisfactory level of decoding is achieved. Turbo codes have been widely used in various communication systems, including satellite communication, deep space communication, and mobile communication. They are also used in other applications, such as magnetic and optical storage systems.
