Improved Performance Scheme for Joint Transmission in Downlink Coordinated Multi-Point Transmission
نویسندگان
چکیده
In this paper, improved performance scheme for joint transmission(JT) is proposed in downlink(DL) coordinated multi-point(CoMP) in case of the constraint transmission power. This scheme is that a serving transmission point(TP) requests the JT to an inter-TP and it selects a precoding technique according to the channel state information(CSI) from user equipment(UE). The simulation results show that the bit error rate(BER) and the throughput performances of the proposed scheme provide the high spectral efficiency and the reliable data at the cell edge. Keywords—CoMP, joint transmission, minimum mean square error, zero-forcing, zero-forcing dirty paper coding.

An Improved Beamforming Schemes in Coordinated Multi-Point Systems
The capacity of modern cellular wireless networks is mainly limited by inter-cell interference (ICI). Coordinated multi-point (CoMP) transmission and reception were adopted as key techniques for Long Term Evolution-Advanced (LTE-A) as they are capable of mitigating ICI through cooperation between several cell sites. Therefore, CoMP techniques provide a significant improvement in cell-edge and a...

The paper deals with the downlink of mobile radio systems, where in each cell an access point communicates with a number of mobile terminals, and where both the access point and the mobile terminals are equipped with multi-antennas. Therefore, the entirety of all downlink connections of each cell constitute a multi-user MIMO system. The considered downlink transmission technique is the recently...

Coordinated Multi-Point transmission/reception (CoMP) can increase the performance of the cell edge users, the spectrum efficiency and mitigate the inter-cell interference among cells. In the CoMP scenario, several base stations which usually need satisfy the cooperating condition serve a single or several cell-edge users cooperatively. As we know, the CoMP techniques can be characterized into ...

In this paper, we provide the analysis of the downlink Coordinated Multiple Point (CoMP) used in conjunction with the basic MIMO. The CoMP is the joint multi-cell transmission from several BS to mobiles, coupled here to an open-loop MIMO technique that does not require the perfect channel state knowledge. We show by simulation, that even for 4 × 4 MIMO transmission, the CoMP can improve the spe...

In this paper, we propose a green radio resource allocation (GRRA) scheme for LTE-advanced downlink systems with coordinated multi-point (CoMP) transmission to support multimedia traffic. The GRRA scheme defines a green radio utility function, which is composed of the required transmission power, assigned modulation order, and the number of coordinated transmission nodes. By maximizing this uti...
