Abstract:
In this letter, we propose a novel slope-based binary modulation called delayed chip slope modulation (DCSM) and develop a chip-based hard-decision receiver to demodulate the resulting signal, detect the chip sequence, and decode the input bit sequence. Shorter duration of chips than bit duration are used to represent the change of state in an amplitude level according to consecutive bit information and to exploit the trade-off between bandwidth and power efficiency. We analyze the power spectral density and error rate performance of the proposed DCSM. We show from numerical results that the DCSM scheme can exploit spectrum density more efficiently than the reference schemes while providing an error rate performance comparable to conventional modulation schemes.
