Optical multiplexing for millimetre-wave MIMO signal transport

Future wireless/mobile systems will increasingly use the available millimetre-wave spectrum, which also lends itself to better frequency re-use, and MIMO/virtual MIMO techniques to enhance throughput. These place significant demands on the fibre part of the access network in terms of transporting high-frequency, wide-bandwidth signals, and multiple “versions” of the signals for the virtual MIMO techniques. In this work, we examine and compare techniques for multiplexing the MIMO/virtual MIMO signals to the antenna units in a distributed antenna/C-RAN type system, ranging from subcarrier multiplexing to dense and ultra-dense WDM and coherent techniques. The work contributes to projects such as RAPID, but is carried out with collaboration from UCL and is particularly supported by a University of Kent 50th Anniversary Scholarship.
