Low Complexity Receiver Detection Techniques for Massive MIMO Systems
Abstract：MIMO has become the key technology in next generation wireless communication systems with its potentially huge advantage to achieve high spectral efficiency. Massive MIMO is an extension of the existing MIMO technology. By applying tens to hundreds of antennas at both base stations and terminals, it is possible to increase diversity order and multiplexing gain, as well as to improve channel capacity and spectral efficiency by dozens of times. However, in Massive MIMO systems, detection complexity at the receiver has become the bottleneck for hardware implementation. This project will mainly focus on Massive MIMO systems, including 1) the design and analysis of Massive MIMO channels, 2) comparison of performance and complexity of different Massive MIMO detection methods, 3) research on high-performance and low-complexity detection algorithms, such as improved sphere detection algorithms. The results of this project will help the development of next generation communications and thus enlighten the deployment of real-world networks.
