Performance Evaluation of Distributed Antenna Systems: Comparison using the COST 2100 Model and Measured Channels

Abstract: Modern wireless technologies strive to meet users' ever increasing demand for high data rates and improved services. One of the most important constraints in wireless system performance is interference. More specifically, the interference caused by serving multiple users in the same geographical area can degrade the link quality greatly. A possible solution to the aforementioned problem it to utilize Coordinated Multi Point (CoMP) transmission and reception techniques. A system that operates using CoMP is capable of dynamically coordinating its transmission and/or reception in order to achieve improved performance. CoMP technology is already adopted by 3GPP for the LTE-Advanced system and numerous studies took place in order to investigate deployment scenarios on that platform. In this work the performance evaluation of different CoMP transmission techniques will be presented. The performance evaluation will be performed using two approaches. In the first approach, the performance evaluation will be based on channel matrices collected from a measurement campaign at Lund University. In the second approach, the different realizations of the channel matrices are generated using the COST 2100 channel model. Then, the results of the two approaches are compared. It was found that, performance evaluation using the COST 2100 can describe the relative performance of the studied CoMP transmission techniques compared to the measurements.
