Electrical engineering MIMO systems Interconnects (Integrated circuit technology)
Current interconnect technology based on wired links is a viable solution in the short term only[17]. Wireless interconnects used in either the radio or optical spectrum suffer from important design complexity constraints [10] [24] [23]. MIMO free space optical communications can be severely limited by optical crosstalk. Crosstalk is a cause of either very wide, unfocused beams of light, misalignment between transmitter and receiver elements, or both. To address this limitation, space-time codes, largely developed for radio frequency channels, have been adapted for use in a free space micro-optical interconnects system and are demonstrated in this thesis. Results quantify the bit-error rate performance and computational complexity of using space time coding for optical interconnects relative to conventional optical interconnect technologies. Consequently, this thesis considers a hardware implementation of space-time coding techniques which sustains data integrity for free space micro-optical interconnects. Coding and decoding the data in a way specific for wireless MIMO systems (adapted for use in optical communications) allows the system to take advantage of high optical bandwidth while introducing various levels of overhead and computational complexity.
