This paper investigates a multiple-valued code-division multiple access (MV-CDMA) technique to achieve efficient data transmission and processing in VLSI systems. CDMA employs a pseudo-random orthogonal m-sequence carrier as a multiplexable information carrier. Orthogonal property of m-sequences enables us to multiplex several computational activities into a single circuit, and execute in parallel using multiplexed data transmission with reduced interconnection. Also, randomness of m-sequences offers the high tolerance to noise interference. In the case of conventional CDMA, however, co-channel interference due to carrier phase offset error severely restricts the available number of multiplexing. In order to eliminate carrier phase offset error, we propose a new class of multiple-valued m-sequences. An application example of neural networks is discussed to demonstrate the feasibility of MV-CDMA in terms of reducing interconnections and eliminating co-channel interference.
