ABSTRACT:
Quasi error free method and system are presented for encoding and decoding information using turbo codes as an inner code in conjunction with an algebraic outer code linked by an interleaver. This combination of outer algebraic code and turbo inner code linked by an interleaver, which has a guaranteed minimum Depth between symbols output from the interleaver, can produce a quasi error free performance in systems utilizing Turbo-Codes without an increase in bandwidth.
