Abstract: This thesis proposes a low-complexity iterative multiuser detection (MUD) algorithm for Time-Hopping (TH) Ultra-Wideband (UWB) communication systems. We implement the maximum a posteriori (MAP) criterion in the detection process by subtracting the multiple access interference (MAI) iteratively. Another contribution is the extension of this algorithm to Space-Time (ST) coded multi-antenna UWB systems. After using the analog ST coding scheme, we can further improve the system performance and deduce the complexity. Computer based simulation results demonstrate that our iterative MUD has a satisfactory BER performance while maintains a considerable low-complexity.
