Design and Analysis of a Packet Scheduler Exploiting the Multiuser Diversity for Performance Enhancement
نویسندگان
چکیده
In this paper, we consider a new packet scheduler exploiting the multiuser diversity in a wireless network with an AMC (Adaptive Modulation and Coding) scheme, and propose an analytic model based on the effective bandwidth theory to investigate the joint effect of the AMC scheme and the packet scheduler on system performance. Based on our analytic results as well as numerical results, we show how to design the packet scheduler to improve the spectral efficiency of the wireless channel.

Packet level performance analysis of a packet scheduler exploiting multiuser diversity
In this paper, we consider a packet scheduler exploiting multiuser diversity in a wireless network with AMC (Adaptive Modulation and Coding), and propose a packet level performance model based on the effective bandwidth theory to investigate the joint effect of the AMC and the multiuser diversity scheduling on the scheduler performance. Based on our performance model and analysis, we investigat...
متن کاملQueueing Delay Analysis for Packet Schedulers with/without Multiuser Diversity over a Fading Channel
In this paper, we focus on a packet scheduling algorithm exploiting multiuser diversity in wireless networks. We compare the delay performance of individual user under the scheduling algorithm exploiting multiuser diversity with that under the round-robin scheduling algorithm in order to reveal the characteristics of the scheduling algorithm exploiting multiuser diversity. For this purpose, we ...
متن کاملStatistical Time-Access Fairness Index of One-Bit Feedback Fair Scheduler
Since the utilization of multiuser diversity in wireless networks can increase the information theoretic capacity, much attention has been paid to schedulers exploiting multiuser diversity. It is known that there exists a tradeoff between the capacity and fairness achieved by schedulers exploiting multiuser diversity. Due to its good balance between the capacity and fairness, the one-bit feedba...
متن کاملPerformance Analysis for Linearly Precoded LTE Downlink Multiuser MIMO
The average channel capacity and the SINR distribution for multiuser Multiple Input Multiple Output (MIMO) systems in combination with the base station based packet scheduler are analyzed in this paper. The packet scheduler is used to exploit the available multiuser diversity in all the three physical domains (i.e., space, time and frequency). The analysis model is based on the generalized 3GPP...
متن کاملCombining Multiuser Diversity and Wcdma Transmit Diversity Modes
Currently there are a number of proposals to extend third generation wireless systems to handle asymmetrical, packet– oriented services requiring high downlink capacities. One such scheme is the high speed downlink packet access (HSDPA) developed within 3GPP WCDMA standardization. This paper studies the performance of multiuser diversity introduced by a certain HSDPA scheduler together with dif...
