We propose a microphone array network that realizes ubiquitous sound acquisition. Nodes with 16 microphones are connected to form a large sound acquisition system that carries out voice activity detection (VAD), sound source localization and sound source separation. The three operations are distributed among nodes using network. Because the VAD is implemented to manage power consumption, the system...

We propose an adaptive electrical dispersion compensation using newly developed high-speed eye monitoring LSI, and demonstrated experimentally the effective enlargement of PMD tolerance in 43 Gbit/s RZ-DPSK signal.
