MATLAB simulation: Algorithm implementation based on turbo encoding and decoding

Encoding and decoding are key links in communication systems, and turbo encoding and decoding algorithms are a commonly used technology with superior performance. This article will introduce how to use MATLAB to implement simulation based on turbo encoding and decoding, and provide the corresponding source code.

1. Introduction to Turbo Coding
   Turbo coding is an iterative coding technique consisting of three main parts: a combinational encoder, an interleaver, and an iterative decoder. The encoder is composed of two identical convolutional code encoders cascaded. The interleaver is used to scramble the encoded data, and the iterative decoder uses iterative decoding to decode.

2. MATLAB implementation of Turbo coding algorithm
   The following is an example source code using MATLAB to implement turbo coding algorithm:
