This paper gives an overview of the so-called link performance model used in TD-LTE (Time Division-Long Term Evolution) system level simulations to determine the link CQI (channel quality Indicator) at reduced complexity of UE (User Equipment). Mainly, effective SINR methods including EESM and MIESM account for the instantaneous channel realization and other configurations and utilize the post processing SINR to compute the effective SNR (Signal to Noise Ratio). Then UE reports CQI values, depending on a linear mapping function from effective SNR to a corresponding CQI value. The simulation shows that EESM and MIESM algorithms bring a similar throughput performance comparing to the ideal CQI choice, but mapping function of EESM method is simpler than MIESM method. Also, EESM method requires all subcarriers to apply the same MCS, which is suitable for TD-LTE system. Therefore, TD-LTE wireless integrated testing instrument adopts EESM method to realize effective SINR link to system mapping.

The chip design based on EDA technology is becoming the mainstream of the electronic system design. The objective of this project is to achieve a better method of the measurement and the multiplication of the measured frequency using the EPM3128. Both the VHDL programms and the timing emulations are achieved detailedly. In order to realized the measurement and the multiplication of the mearsured frequency, the synchronization should be achieved. The number of the crystal oscillator signal is been recorded, and then the CPU reads the data in the counter through the fip-latch. What's more, because of the n-bit right shift, the data recorded in the measurement is reduced to the 1/2n times. A narrow pulse will be outputted each time a expiration of the counter arrives.

In order to solve the problem of GA's slow convergence in the VQ codebook design due to the strong global search ability and the complex computation, a hybrid algorithm based on the GA-LBG algorithm is adopted because the LBG algorithm as an iterative algorithm based on the nearest neighbor rule and the centroid rule owns the advantage of fast convergence. In the simulation experiment, MFCC extracted from Mandarin, Shanghainese, Cantonese and Hokkien are employed as the feature vectors to establish codebook models with GA-LBG for the dialect identification, and the recognition performances on different size of the VQ codebooks are studied. And simulation results demonstrate that the running time with GA-LBG reduces to 1066.4s, less than that with GA alone.

For the limitation of data transmission bandwidth and real time transmission demand, generally image compression is required to implement the precise and flexible rate control algorithm. Rate control is an important issue in the image compression field. This paper considers the problem of rate allocation to each encoded segment for CCSDS image compression. One straightforward method is to allocate an equal amount of rate to each segment based on the average of the total number of compressed bytes. The obvious drawback of this method is that different segment will be reconstructed to different quality, so the overall quality of the reconstructed image will not be optimized. For the shortage of the original rate control method, as to improve the overall quality of the reconstructed image, an improved rate control algorithm is proposed for CCSDS image encoding. The key component of the proposed rate control method is the appropriate rate allocation. Experiments on the test images show that the PSNR can be increased at about 0.3dB on average, compared to the original algorithm. Therefore, experimental results confirm the effectiveness of the proposed algorithm in terms of objective evaluation, and the rate-distortion performance of the reconstructed image is improved.

With the increasingly shortage of conventional energy, solar energy, as one kind of an inexhaustible, and pollution-free clean source of energy, became the first choice of renewable energy. This paper designs an attitude automatic adjusting system which makes the solar panels perpendicular to the solar incidence line during the day to increase the absorption efficiency of solar energy. The system combines program control and sensor control to track the solar, and the working mode of the system is depended on by photodiode and algorithm of sun time. In different working circumstances, the system could work in different working modes: calendar-check tracking mode, four-quadrant detector tracking mode and night mode. Practical experiments show the system could meet the demands of detection accuracy, lower power, and higher reliability.
