In this paper we address a fundamental question in communication, that is, in the presence of various noise scenarios such as white/colored Gaussian noise and impulsive -type noises, how to efficiently and accurately transmit a set of various signals either they are speeches or images from one side into another via a communication channel? We need to manipulate the various signals in a way so that they are more robust to different types of noises while at the same time the set of signals can be efficiently and accurately transmitted into another side via a communication channel. In this paper we propose a spatial-temporal spreading method for a set of signals and show its applications in communications.
