In this paper we evaluate a recently proposed multiple-input multiple-output (MIMO) system called the Layered Steered Space-Time Codes (LSSTC). The LSSTC system is evaluated for multi-user environments where scheduling can be used to increase the system capacity by harnessing the multi-user diversity. This evaluation is done by comparing the capacity and the probability of error for several combinations...
An improved scheduling algorithm is proposed for optimizing the sum-rate gain in a multiuser Multiple-Input and Multiple-Output (MU-MIMO) downlink system with limited feedback and Block Diagonalization (BD) precoding. A low bits feedback for user selection is followed by a high bits feedback to improve the system sum-rate capacity. Based on our analysis and the simulation result, it shows that the...
Due to the strict time constraints, the real-time services for multimedia applications in wireless networks are difficult to deal with as a packet scheduler schedules the related packets. The system performance of a base station (BS) mainly also depends on the packet scheduler policy. So far as our knowledge, the relatively existing packet scheduler schemes arrange the packets based on the corresponding...
