We discuss a method for sparse signal approximation, which is based on the
correlation of the target signal with a pseudo-random signal, and uses a
modification of the greedy matching pursuit algorithm. We show that this
approach provides an efficient encoding-decoding method, which can be used also
for lossy compression and encryption purposes.
