Algorithms for Coordinated Multipoint Techniques

The main concepts of coordinated multi‐point (CoMP) are introduced. With its distributed remote access units and central processing unit, the FUTON architecture is especially well suited for the application of such techniques that coordinate the transmission and reception of distributed antennas to make use of inter‐cell interference. While non‐linear techniques are proven to yield maximum performance, we concentrate on linear techniques due to the good tradeoff between performance and complexity. After introducing the main concepts, we demonstrate the potential of these techniques, by means of simulation results and measurements from a prototype system that also employs the proposed radio‐over‐fiber technology.
