An eight-dimensional signaling scheme for bandlimited channels

摘要

The demand for higher handwidth and power efficiencies in digital communication makes multidimensional modulation schemes increasingly attractive.In this paper we introduce one such scheme,called 8D-4P2C (for 8 Dimensions,4Pulses,and 2 Carriers).This scheme has a compact spectrum and is easily implementable.Moreover,it is amenable to a simplified detection scheme with a arginal loss of effficiency with respect to optimum demodulation.Its performance,obtained by computer simulation,proves its attractiveness for digital radio systems.
