In this paper, the stability problem of bilateral tele-operation systems with data sampling and communication time delays is considered. Two buffers are introduced in the bilateral teleoperation control framework to deal with the issue that the information transmitted between the master and slave sides suffer from time-varying delays. The mathematical model of bilateral teleoperation systems based...
This paper investigates the spatial multiuser scheduling strategies that apply different pairing criteria to select a pair of users carrying out transmission simultaneously in virtual MIMO (VMIMO) systems. Five kinds of criteria are described and compared, which are categorized as channel correlation minimization, bit error rate (BER) minimization and capacity maximization depending on their diverse...
A fairness adjustable grouping (FAG) multiuser scheduling algorithm based on MMSE-SIC (minimum mean square error-successive interference cancel) receiver is proposed for MIMO MAC (multiple access channel). The implementation in the 3GPP LTE VMIMO (virtual multiple input multiple output) systems as pairing scheduling (PS) is discussed. This algorithm makes use of the proportional fair (PF) scheduling...
