You can also use Turbo codes in other applications that require reliable information transfer over bandwidth- or latency-constrained communication links in the presence of data corrupting noise.

Since the algorithms needed to implement the decoders have been well documented by others, they are only referenced here, not described in detail. concatenated codes that utilize turbo code as inner codes and rectangular parity check code (RPCC) as outer codes is investigated with reliability-based hybrid ARQ (RB-HARQ). Also, we investigate the performance of turbo codes with RB-HARQ and rate adaptation.

The turbo code encoder is a parallel concatenation of two recursive systematic convolutional (RSC) codes, separated by an interleaver. This chapter shows the construction of a RSC encoder from a nonrecursive nonsystematic (conventional) convolutional encoder.
