We propose a digital clock recovery algorithm and demonstrate its tolerance to at least 5GHz laser frequency mismatch in a 43Gb/s DP-RZ-QPSK receiver after 1200km transmission.- We propose a digital clock recovery algorithm and demonstrat

In this dissertation, there are four main aspects included: energy reservation on MAC layer, secure improvement for DoS attacks on MAC layer, query processing with uncertainty for sensor systems, and throughput maximization on MAC layer for ult
