Initial experimental results of nanosecond-range multiple-pulse synchronization controlled by magnetic switches on a communal magnetic core were presented in detail in this paper. Magnetic switches on a communal core are designed, and different experiments for the multiple-pulse synchronization tests are also put forward. The central principle is that the communal magnetic core compels the multiple...
A modified loop filter structure for symbol synchronizer with reduced timing jitter is proposed. A moving average unit (MAU) is added to the traditional proportional-integral (PI) structure to form the modified loop filter. Since the variance of the noise is limited under the average operation, timing jitter is reduced efficiently. Furthermore, the structure is easy for implementation, which requires...
In multilevel pulse amplitude modulation (PAM) and quadrature amplitude modulation (QAM) systems, there is a strong demand for a reliable and precise timing phase provided by the timing recovery circuit. However, reducing timing phase jitter just by narrowing the bandwidth of the timing recovery loop will decrease the capability of tracking the time variant channel. To avoid this drawback, the only...
