Effect of Feedback Errors on Joint MS-GSC combining and Multiuser Downlink Scheduling
Closed loop adaptive modulation systems rely on a feedback channel to receive channel state information from the users and set according to it the appropriate modulation index. In [1] three joint adaptive modulation and combining scheduling schemes are suggested to manage the wireless resource between many users in a multiuser diversity environment. The assumption that was made in that work is ...
متن کاملJoint Minimum Selection GSC and Down-Link Power Control
Abstract— We propose and analyze in this paper a new adaptive power controlled minimum selection generalized selection combining (MS-GSC) diversity scheme termed joint combining and power control (JCPC). The key idea is to meet the required quality of service while using the minimum possible transmit and processing power. Four power control variants accounting for practical implementation const...
متن کاملMinimum Selection GSC with Down-Link Power Control
We propose and analyze in this paper two new adaptive power controlled minimum selection generalized selection combining (MS-GSC) diversity schemes. The key idea behind these two schemes is to request the transmitter to vary its power level during very adverse channel conditions in order to communicate with the minimum required quality of service. For each scheme, four power control variants ac...
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...
متن کاملTransmitter-based Joint Nonlinear Multiuser Interference Cancellation and Multipath Diversity Combining for DS/CDMA Systems
A nonlinear transmitter-based multiple access interference (MAI) cancellation technique, Tomlinson-Harashima transmitter precoding (THP), is proposed for Direct Sequence (DS) Code-Division Multiple Access (CDMA) systems with or without multipath fading. This zero forcing (ZF)-based transmitter precoding method minimizes the mean square error at the receiver. It is suitable for the downlink si...
