This paper aims for high reliability as well as reduction of hardware size, cost and development period for the time-division multiplex access (TDMA) equipment, and proposes a new TDMA equipment architecture and modular construction. The fundamental approach employed in this paper is the digital realization of the analog circuit and the LSI implementation of the digital circuit. Then to realize TDMA equipment with a simple architecture and to realize a widely applicable LSI, TDMA equipment is reconstructed into a hardware-oriented architecture. Based on the new architecture and the optimal function assignment to the modules, the following LSI and IC were developed: six types for synchronization control; 11 types of LSI and IC for modulation-demodulation; and 1 type of terrestrial network interface.
