Coherent detection, a field revived by advances in DSP, has recently received renewed interest in optical communication systems with spectrally efficient modulation formats. We review DSP techniques for 16-QAM which is one of the most promising modulation formats for next-generation communication systems.

Multicore architecture has been widely exploited in computing systems to increase performance under power-constrained environment, and realized the highest-performance supercomputers [1]. Mulicore systems are high-level integration of many power-efficient microprocessors with high-bandwidth interconnects, which requires high data rate per channel, high channel counts, or both. Optical transmission is inherently suited for high-bandwidth interconnects with low propagation loss as well as low dispersion, and the latest top-performance supercomputers have exploited many optical channels [2]. Recent advancements in optical interconnect technologies have demonstrated high-density packaging as well as low-power dissipation of high-speed optical channels, both of which are superior to electrical counterparts.
