Abstract :
In this paper, a novel modulation format is proposed for time-hopping pulse position modulation (TH-PPM) ultra wideband (UWB) communications, where a near-orthogonal set of user-specific TH codes is employed for M-ary code shift keying (MCSK) to carry additional data. A particular TH code, selected by log2 M-bit data, modulates the basic pulses that are time-shifted by binary PPM (BPPM), resulting in combined MCSK and BPPM (i.e., MCSK/BPPM). The combined modulation can achieve a high data rate without affecting pulse shaping and further improve the bit-error-rate (BER) performance subject to the same signal energy per bit.
