Complexity Reduction of Maximum-Likelihood Multiuser Detection (ML-MUD) Receivers with Carrier Interferometry Codes in MC-CDMA
—We propose to use carrier interferometry (CI) codes to reduce the complexity of the maximumlikelihood multiuser-detection (ML-MUD) receiver in MC-CDMA systems with carrier frequ...

Time-Hopping UWB Multiuser Detection Using Adaptive Multistage Matrix Wiener Filtering Schemes
— Adaptive reduced-rank (RR) multistage matrix Wiener filtering (MMWF) techniques, based on the minimum mean-square error (MMSE) criterion, are proposed for timehopping (TH) pul...
