The design of the code reference points for photogrammetry.

In view of the problem that an incremental encoder must perform the zero-finding to establish its mechanical origin when it starts to work in the case of absolute positioning, the paper proposes a novel zero-finding algorithm based on the unique coding mechanism of the incremental encoder with the distance-coded reference mark.

Research on LTE's reference signals of uplink

Based on ICA algorithm with reference signals,a method of removing blinking artifacts was proposed in this paper.

The ensemble average is applied to acquire the normal EPs as the reference signal for the adaptive time delay estimation (TDE).

The results show that when selecting vibration signals as reference signals,the selection of reference signal depends not only on the correlation,but also on the distribution of vibration energy.

Independent component analysis with reference(ICA-R) can extract only some desired source signals from mixtures of all source signals by incorporating prior information into the learning algorithm as reference signals.

Hopping-frequency communication is often used in military Satellite Communication(SATCOM) systems,which may lead to the difficulty in coherent detection Phase Shift Keying(PSK) signals unless many reference symbols are added to aid the phase estimation of the received signals.
