  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.
