A new method of signal encoding, called MRAC coding, is proposed based on Model Reference Adaptive Control (MRAC) system theory. Under certain limited situation, it is aimed to explore a way to attain higher system performances by introducing a new account for the effect of the quantizer nonlinearity. Though the MRAC coding is a kind of so-called waveform coding, it is not a form of predictive coding, but, say, control coding. In the system, pulses, which control the output of a system having pole-zero transfer function to follow the given signal, are determined and quantized to send to the receiver. The MRAC coding is considered, in principle, to be applicable to encode a variety of signals. The present paper is intending to give the detailed and unified theory of the MRAC coding and to check its feasibility through the experimental studies.
