—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)
— 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 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)
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)
The augmented-reality (AR) applications built using unmodified ARToolkit are limited in that the marker patterns and 3D models must be built into the applications themselves, and so are limited in number. We propose a solution to bypass this limitation by integrating ARToolkit with a 1-D barcode reader assisted by an Adaboosted classifier and accessibility(More)
