Abstract

A TDMA (time-division multiple access) system which adopts the TCM (time-compression multiplexing) technique is proposed for application to cellular systems. The significant advantages of the TCM over the FDM (frequency-division multiplexing) system when used in the narrowband single channel per carrier are demonstrated with respect to the frequency spectrum efficiency. The intention is to develop a communication format that would be applicable to cellular systems. The application of the time-compression technique to analog signals is fused with the digital technique, and thus a modulation format of cellular or microcell systems that maintains the advantages of analog systems is developed
