—This letter presents a joint scheme of receive antenna selection and symbol detection for multiple-input, multiple-output (MIMO) systems based on the maximum likelihood (ML) criterion. To mitigate the computational complexity, a novel variant of the genetic algorithm (GA) is addressed to solve the nonlinear optimization involved, where a new heterogenous(More)
This paper presents an effective space-time multiuser detection (MUD) with the assistance of soft information in multipath code division multiple access (CDMA) channels. The space-time MUD considered is a separable spatial-temporal filter which consists of a single spatial filter and temporal filter. The soft information determined from the previous(More)
— This paper proposes a simple, yet effective generalized sidelobe canceller (GSC)-based Capon multiuser receiver for the Alamouti space-time block coded (STBC) multiple-input multiple-output code-division multiple-access (MIMO CDMA) systems. The new receiver makes full use of the space diversity provided by the antenna array and the time diversity provided(More)
— In order to simultaneously combat both of the inter-carrier interferences (ICIs) and multiple access interferences (MAIs) to achieve reliable performance in multi-carrier code division multiple access (MC-CDMA) systems, this paper proposes a new scheme for joint frequency offset estimation and multiuser symbol detection. The new approach is based on the(More)
This paperpresents a hybrid of the minimum mean square To improve the performance impaired by the propagation er-error (MMSE) multiuser detection (MUD) and successive inter-rors and grouping effect, in this paper we further our previous work ference cancellation (SIC) in conjunction with an information reuse of [5] by adding in an information reuse scheme.(More)
— This paper presents an effective multiuser detector (MUD) for the uplink of dual-signaling multiple-input multiple-output (MIMO) code division multiple access (CDMA) systems over multipath fading channels, where the data are transmitted using either the spatially multiplexing (SM) or the space-time block code (STBC) scheme. The new MUD first separates(More)
