Optimized impulse correlation technique to mitigate the MUI at UWB-TR receiver

Ultra-wideband (UWB) communication techniques are highly interesting because they seek to rearrange the huge spectrum of UWB for diverse applications. Therefore, UWB is the main technique employed in communication systems for 4G wireless networks. However, several issues in UWB technology, such as interference with various existing civil and military communication systems, require resolution. In this study, the number of impulses (M) obtained from a pulse is optimized to implement a special correlation technique called optimized impulse correlation (OPIC). The UWB transmitted-reference (TR) receiver correlates all impulses in the pulse. The new technique contributes to the reduction of multi-user interference (MUI), especially in concurrent schemes. According to the OPIC curve, a value of M from (M = 1, 3, 5) is the most suitable to eliminate MUI in the TR receiver, not a value of M from (M = 7, 9,..., 49).
