This paper explores the performance of both source coding and error-correction in a single coding step. Such joint source-channel coding is done here using codewords of varying lengths that have particular distance properties with each other, which allows error detection and correction. Hence, these codes are called Variable-Length Error-Correcting (VLEC) codes. These codes exhibit memory like convolutional codes but spatial memory according to the variable-length nature. These (VLEC) codes are used in image coding and show sub error performance over variable length source coding such as Huffman code.
