In this paper, we propose a bit and power allocation strategy for adaptive modulation and coding (AMC) based spatial multiplexing multi-input-multi-output (MIMO) orthogonal frequency division multiple access (OFDMA) systems. This strategy aims to maximize the average system throughput by allocating the available resources optimally among the utilized bands depending on the corresponding channel conditions...
This paper presents a quantitative performance analysis of the dual-cell high-speed downlink packet access (DC-HSDPA) operation focused on the gain achieved by pooling the radio resources of two carriers in the same base station and enabling a collaborative operation (joint-scheduling) on the lower radio layers.
IEEE 802.16j multi-hop relay task standard includes two mutually exclusive options: transparent relay stations (T-RS) and non-transparent relay stations (NT-RS). In this work, a system design approach is proposed to compare different relay systems in term of their capacity with rate fairness constraint among the mobile stations (MS). Single-input single-output (SISO) and multi-input multi-output (MIMO)...
In this paper, power allocation scheme for clusters by mobile station (MS) is investigated in the uplink of a multi-user multiple-input multiple-output (MU-MIMO) and orthogonal frequency division multiplexing access (OFDMA) cellular system. In system level simulation works, without the knowledge of how many clusters will be assigned to a MS, it is a puzzle to decide how much transmission power should...
