In this paper, we propose a novel noncoherent UWB (de)modulation system, which uses a pair of orthogonal pulses to convey information symbols. Same as the original noncoherent UWB [1], our approach remains operational even without timing and channel estimation. Moreover, due to the orthogonality between the received waveforms of the pulse pair, our approach results in a differential demodulator. This means that our approach does not need Viterbi decoding which is required by [1], even in the presence of timing error. Simulations are also carried out to corroborate our theoretical analysis.
