MATLAB Implementation of Channel Coding Techniques

MATLAB programs implementing various channel coding techniques: CRC cyclic redundancy check, Reed-Solomon (RS) codes, convolutional codes, turbo codes, and trellis coded modulation (TCM). Channel coding is a fundamental technique used to enhance communication system reliability, widely employed in wireless and digital communication systems. CRC codes utilize cyclic redundancy check algorithms for error detection in data transmission, typically implemented using polynomial division operations. RS codes are powerful error-correcting codes capable of both detecting and correcting transmission errors through finite field arithmetic operations. Convolutional codes employ linear time-invariant systems with shift registers and XOR gates, commonly used in high-speed data transmission scenarios. Turbo codes feature iterative encoding and decoding processes using parallel concatenated convolutional codes with interleavers, delivering superior bit error rate performance. TCM combines modulation and coding techniques to improve both transmission reliability and spectral efficiency through signal set expansion and trellis-based mapping.
