The present invention is directed to a simplified digital subband coder/decoder. In the present invention a signal is fed into a coder. The coder uses a non-orthogonal algorithm that is simply implemented in the coder hardware. The simple non-orthogonal design is then used in the implementation of the decoder to decode the signal.
