In this paper, we propose a method to minimize the Multi-User Interference (MUI) caused by multiple access (MA) in a Time Hopping Ultra Wide Band (TH-UWB) system with line-of-sight (LOS) multi-path channel in a residential environment IEEE 802.15.4a channel model. We considered synchronous case over an Additive White Gaussian Noise channel (AWGN). The problem is formulated as a combinatorial optimization...
Recently, a block spreading code division multiple access (BS-CDMA) technique was presented whereby user-specific preceding along with orthogonal spreading codes are used to achieve multi-user interference (MUI) free when all users arrive at the base station simultaneously. In practice however, imperfect synchronization destroys the orthogonality among users and MUI occurs. This paper investigates...
