Recently, coordinated multiple point transmission/reception (CoMP) is proposed to overcome the performance degradation due to the inter-cell interference (ICI) in a multi-cell environment. In this paper, we present a multiuser MIMO-BC technique with limited feedback, and propose the novel codebook for cooperative beamforming to reduce the ICI. Based on the proposed codebook, an orthogonal beamforming...
A recent dynamic increase in demand for wireless multimedia services has greatly accelerated the research on dynamic channel adaptation of high quality video applications. In this paper, we explore a theoretical approach to cross-layer optimization between multimedia and wireless networks by means of a quality criterion termed ldquovisual throughputrdquo for downlink video transmission using a layered...
FRPA(frequency reuse power allocation) technique by employing the frequency reuse notion as a strategy for overcoming the ICI(intercell interference) and maintaining a QoS(quality of service) at the cell boundary is described for broadband cellular networks. In the scheme, the total bandwidth is divided into sub-bands and two different power levels are then allocated to sub-bands based on the frequency...
In this paper, we evaluated effects of ICI (inter-cell interference) on an OFDM (orthogonal frequency division multiplexing) based wireless communication system's reverse link capacity and suggested macroscopic diversity oriented resource allocation scheme to reduce interference and enhance reverse link capacity. For this, the exact amount of ICIs in the system is measured and represented as a closed...
A cell planning technique termed BRD (bandwidth and region division) is presented for overcoming interference, maintaining QoS (quality of service) and improving channel capacity over OFDM (orthogonal frequency division multiplexing)- based broadband cellular networks. Through an optimal combination of sectorization and zero padding, bandwidth and region division is achieved that minimizes the outage...
