Improved Gardner Suppression Timing Jitter Synchronization Algorithm

Coarse Symbol Timing Synchronization Improved Algorithm for CMMB Mobile TV

There are some multipath and frequency offset in wireless transmission environment, in order to determine the correct starting position of each OFDM symbol, CMMB system must achieve accurate symbol synchronization for sending and receiving data, making FFT data transform window position in receiver consistent with IFFT window position in sender. This paper combined the specific frame structure ...

Timing and phase jitter suppression in coherent soliton transmission.

We have revisited soliton transmission in the new context of coherent optical detection optimizing and comparing digital backward propagation and in-line optical filtering as a means to suppress soliton timing and phase jitter. We find that in-line optical filtering allows one to improve the reach of the soliton system by up to the factor of 2. Our results show that nonlinear propagation can le...

Study on OFDM Symbol Timing Synchronization Algorithm

OFDM technology has become the core technology of the next generation mobile communication system because of the high bandwidth efficiency, the strong ability to resist inter-carrier interference and anti-channel interference. However, because OFDM system is a multicarrier modulation system, the system will be very sensitive to its synchronization errors. Synchronization estimation is an import...

Modeling Timing Jitter in Oscillators

Timing jitter in oscillators is a key factor determining the phase noise performance of phase-locked loops. This paper reviews a theory of phase noise in oscillators, and presents timing jitter models suitable for discrete event simulation of these systems.
