Then,based on gait tracking,the gait planning of BRHL is described in detail for simulation.

The analysis and simulation showed that the frequency offset efficiently estimated was little but accurate, and the algorithm was suitable for carrier frequency synchronization tracking, could work well in the environm.

A new method of synchronization tracking is proposed.

The theories of synchronization acquisition and synchronization tracking in a non-coherent FH/MFSK communication system are introduced in this paper,based on maximum-likelihood rules, the synchronization tracking estimation of time and frequency is discussed,using the methods of time dividing averagely and frequency displacing.

A synchronous tracking measurement method for different capacitance capacitors.;

The paper emphatically analyzes the technique and theory of synchronous track of locking phase of fast changing-over at any time between main power supply and stand-by by a static switch.
