As many practitioners know, compressed streams are very sensitive the transmission errors. Even a single error can have devastating effects and compromise all the data downstream. In fact, the non-resilience of adaptive data compression has been a practical drawback of its use in many applications. Joint source-channel coding has emerged as a possible solution to this problem. Usually, joint source-channel coding trades source bits for channel bits or vice versa, and more than often requires some adjustments in source coding and channel coding parts. This paper deals with a very popular compression scheme, namely the so-called Lempel-Ziv-Welch (LZW).
