Theoretical investigation into spectral coexistence of CDMA and TDMA systems

Abstract EN

The scarcity of available radio spectrum presently limits the extension of modern multimedia sys-tems.

This paper presents a theoretical investigation into the possibility of using a frequency overlay of a nar-rowband Code Division Multiple Access (CDMA) System and a Time Division Multiple Access (TDMA) System to provide a greater spectral efficiency.

This paper shows that under certain conditions the two systems can operate in the same frequency band and in the same area with a considerable improvement in the overall capacity of the whole system.
