An FPGA based transceiving synchronization method is demonstrated for Free Space Optical (FSO) communication system
which is discussed separately as the transmitting protocol and the receiving protocol. During the discussion of these two parts
the co-operation of them is also discussed. The transmitting protocol interfaces the outer input data with a parallel port
buffers the input data
encodes the input data stream
serializes the parallel data and outputs the serialized data. It also has an output management unit to manage the activity of each part of the transmitting protocol. The receiving protocol filters and synchronizes the input serial data stream
parallels the serial data stream
decodes the input data
checks received error
handles transmission exception and interfaces the outer receiver with a parallel port. The entire transceiving protocol could be programmed into a single FPGA chip to improve system integrity and reduce the system cost. The presented protocol could be taken as "protocol transparent" for outer interfaces
meaning that when interfacing the presented system to an outer system
users don't have to consider what protocol the outer system transceiving data stream is under
for example
the TCP/IP protocol or anything else
in the case that its I/O interface is a parallel port. Simulation and final experiment prove that the protocol presented is a working solution at a certain bit rate scale. 2012 IEEE.

In order to resolve the poor suppression capability of noise and fitter interference existing in grating encoder high-rate subdivision and the poor accuracy of kam-to
counting circuit
the results show that the design method will help improve the controlled object of measurement precision and control accuracy. 2010 IEEE.
we design a circuit based on FPGA to realize multiplier
kam and filter for the output of two-way orthogonal signal generated by Incremental Optical Encoder. The system is mainly divided into three modules such as filtering
multiplier kam-to and counting. The main function of filter circuit is to eliminate the jitter and noise interference existing in the quadrate encoder signals. Kam-to multiplier circuit can accurately judge the full cycle and half-cycle of incremental encoder
at the same time can make fourfold multiplier. Counting circuit can use IP cores owned by Quartus II which is not restricted on the median. At last
timing simulation based on Modelsim carried on the three modules

X-ray coherent scatter imaging is a novel imaging technique. A clinical X-ray coherent scatter imaging equipment based on image processing method is introduced
adopting CR and IP plate instead of the diffractometers. The scatter images obtained are made of some circles with the same center. According to our equipment
it is vital to calculate the energy template to classify the different samples. However
it is difficult to separate them using the traditional threshold method due to noise and overlapped shadow. Markov Random Field (MRF) is employed to segment the scatter image
which takes spatial information into account to deal with the noise and overlapped shadow. The experiment results show our method is reasonable and feasible.
