Performance evaluation of CoMP transmission schemes using measurements versus the COST 2100 channel model

Abstract

Coordinated Multi Point (CoMP) transmission and reception techniques are used in order to improve the performance of single or multiple cells in wireless systems. A system using CoMP techniques is capable of jointly optimizing its transmission and/or reception and, hence, achieving higher performance. In this work, performance evaluation of three CoMP techniques are performed based on simulations using the COST 2100 channel model and also based on measured channels collected from a synchronous multi-link measurement campaign at Lund University. The contribution of this work is twofold. First, the performance evaluation of different CoMP transmission techniques, namely, the Joint Processing, the Partial Joint Processing and the Coordinated Beamforming, are presented. Second, the capability of the COST 2100 model in predicting the relative performance of different CoMP techniques is assessed. It was found that the COST 2100 model is capable of estimating the relative performance of the studied CoMP schemes well. Moreover, detailed comparison highlighting the agreements and discrepancies between the performance results based on the measured channels and those based on the COST 2100 model are reported.
