Approximate discrete time analysis of the hybrid Token-CDMA MAC system

Author: Liu, YS ; Takawira, F ; Xu, HJ Date: Sep 2007 In this paper a hybrid Token-CDMA based medium access control (MAC) protocol is considered. The MAC scheme is analytically modelled as a multiserver multiqueue (MSMQ) system in the case of a gated service discipline. The authors present an ... Read more
Optimization of hybrid token-CDMA MAC system using cross-layer information

Author: Liu, I-S ; Takawira, F ; Xu, HJ Date: Aug 2007 This paper presents a joint medium access control and physical (MAC-PHY) layers solution for optimizing the system performance in the hybrid Token-CDMA MAC system. The proposed scheme is designed in order to provide continuous monitoring of ... Read more
Performance analysis for a QoS-aware hybrid token-CDMA MAC protocol

Author: Liu, YS ; Takawira, F ; Xu, HJ Date: Sep 2007 This paper presents the performance analysis of a hybrid Token-CDMA MAC protocol. The protocol is based on a token passing scheme with the incorporation of code division multiple access (CDMA). The protocol provides both QoS guarantee and ... Read more
Performance evaluation of high rate space–time trellis-coded modulation using Gauss–Chebyshev quadrature technique

Author: Sokoya, O ; Xu, HJ ; Takawira, F Date: May 2008 The performance analysis of high rate space–time trellis-coded modulation (HR-STTCM) using the Gauss–Chebyshev quadrature technique is presented. HR-STTCM is an example of space–time codes that combine the idea used in trellis coded modulation ... Read more
Super-Orthogonal space-time trellis codes for virtual antenna arrays

Author: Sokoya, OA ; Xu, H ; Takawira, F Date: Sep 2006 This paper investigates the performance of super-orthogonal space time trellis codes when Virtual Antenna Arrays (VAA) is employed. The concept of virtual antenna arrays was developed to emulate Multiple-Input Multiple-Output (MIMO) schemes ... Read more
