Abstract :
This paper presents a concept under development, that of dynamically coloring the spectrum of a pseudorandom spreading code in order to aid slow rate data communication in a very poor channel. The method seems to hold promise for some difficult industrial communications problems, especially for wireless random access communications in time varying noisy channels that are difficult to effectively model and are resistant to conventional approaches
