IMPLEM THE HIGH SPEED MODEM W/MULTILEVEL MULTIDIMENSIONAL MODULATION-TMS320C542

This paper presents the high speed modem with multilevel multidimensional modulation.

The multilevel linear combination of shifted prolate wave spheroidal functions with dual orthogonality is used as information carrying signal. It enables transition from two-dimensional basis (Phase Shift Keying, Quadrature Amplitude Modulation) to more dimensional basis (Multilevel Multidimensional Modulation).

The use of this basis increases information speed and/or noise stability. The shifted prolate wave spheroidal functions are solutions of the special integral equation.

The new features of the Texas Instruments (TI(TM)), TMS320C542 Digital Signal Processor (DSP) make implementation of a high-speed modem, more effective.
