A New Hardware Design Scheme of Symbol Synchronization for an Underwater Acoustic Receiver
2011 Third International Conference on Measuring Technology and Mechatronics Automation
Conventional time domain symbol synchronizers typically use channel noise models to set static synchronization thresholds. However, static thresholds may prove insufficient in the underwater environment as the underwater acoustic channel can be highly variable and plagued by multipath, variable noise levels, path-loss, Doppler shifts, and long propagation delays. The paper provides a new hardware scheme using real time orthogonal sliding correlation as an adaptive threshold to build a symboldoi:10.1109/icmtma.2011.45 fatcat:xeawnew2hre2ho2qx2xcpzhqg4
