Author:Liu, YS; Takawira, F; Xu, HJDate:Sep 2007In 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
Author:Liu, I-S; Takawira, F; Xu, HJDate:Aug 2007This 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
Author:Liu, YS; Takawira, F; Xu, HJDate:Sep 2007This 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
Author:Sokoya, OA; Xu, H; Takawira, FDate:Sep 2006This 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
