TLDR
The present solution gives an optimum algorithm for effective transfer of image codings over a wireless medium and carries coherent implementation of predictive, DPCM and Huffman Coding.Abstract:
The present solution gives an optimum algorithm for effective transfer of image codings over a wireless medium. In this paper, the logic behind generating Huffman codes for the gray symbols of an image, its transmission over an AWGN channel and decoding the received code is practically analysed. The coding utilizes a main MATLAB file with associated function to carry out subsequent tasks. The solution carries coherent implementation of predictive, DPCM and Huffman Coding.read more
