Turbo Decoder
Decode input signal using parallel concatenated decoding scheme
Libraries:
Communications Toolbox /
Error Detection and Correction /
Convolutional
Description
The Turbo Decoder block decodes the input signal using a parallel concatenated decoding scheme. The iterative decoding scheme uses the a posteriori probability (APP) decoder as the constituent decoder, an interleaver, and a deinterleaver. The two constituent decoders use the same trellis structure and decoding algorithm. For more information, see Parallel Concatenated Convolutional Decoding Scheme and APP Decoder.
