In this paper, we present a new type of receiver for MIMO optical wireless communications. The new receiver consists of multiple receiving elements (REs), each made up of a photodetector (PD) placed under an aperture. The directionality of each RE is shown to depend on the relative position of the PD and the aperture. Receiving patterns are calculated for various MIMO receiver designs, demonstrating that significant angular diversity can be achieved within a compact receiver structure. Simulation results are presented for a number of typical indoor scenarios when the transmitted signals are modulated using asymmetrically clipped optical OFDM (ACO-OFDM). For the scenarios considered, the bit error rate is lowest in the middle of the room and highest in the corners. The results indicate that for typical parameter values, reliable communication can be achieved throughout the room

Other2015 IEEE International Conference on Communications (ICC2015), held in the magnificent city of London, the UK’s capital. ICC2015 will be an excellent presentation, networking and publicity event, offering the opportunity for researchers, engineers and business people to meet and exchange ideas and information. In addition to the traditional keynote, symposium, workshop, tutorial and industry forum sessions, this year we are offering a new event – Chief Technology Officer Forum - during the plenary session. Here, the future of mobile networks will be discussed.
