Hi,guys.a signal model of UWB time-hopping system
a typical time-hopping format of the kth impulse radio transmitter output signal
S(u,t) is given by this equation in many papers:
S(u,t)=∑ω(t-jTf-Cj(u)×Tc-dj(u)) ( -∞<j<∞ )
where ω(t) represent the transmitted monocycle waveform that normally begins at time zero on the transmitter clock,Cj(u) a TH sequence.
but I want to know what does dj(u) mean and what factors cause it?
