Wireless sensor network is a new technology with sensation ability, the computing power and the wireless communication ability. On the basis of analysis of the existing positioning algorithm of wireless sensor network, this paper proposes a new algorithm based on RSSI positioning, and introduces a space formula stratified. The experimental results show that this algorithm can cope with tracking function better.

With the rapid development of the SoC integration technology, multi-core digital signal processors (DSPs) are becoming increasingly demanded in recent years. Then, running and debugging the parallel programs on multi-core DSPs are becoming more and more complicated as well. So, the efficient debugging method for the parallel programs has become a key factor to determining the development period for a parallel software. Therefore, it is significant to study the debugging scheme based on JTAG protocol for multi-core DSPs. In this paper, aiming at the debugging problem for multi-core DSPs, a parallel JTAG-based debugging and selection scheme has been proposed, which is also compatible with the Universal Serial Bus (USB) interface. The experimental results show that this scheme has advantages in the multi-core debugging framework optimization and communication mechanism optimization, greatly reducing the parallel program development period and improving the resource utilization.

The signal reception mode of ultra wideband (UWB) system is similar to the traditional signal transmission and reception mode. However, the system is extremely sensitive to the noise error, which has different impacts on the clock error in different systems and has a great impact on the clock frequency offset. Therefore the error analysis of three transceiver modes are carried out: one-way time flight method (OW-TOF), two-way time flight method (TW-TOF), two-way bilateral time flight method (SDS-TWR). The simulation results show that the mode which has the smallest ranging error is the SDS-TWR, and the mode of largest one is OWTOF. But the SDS-TWR system is the most complex system of them, while The OW-TOF is the simplest one. The TWTOF is very sensitive to clock skew. When the clock frequency offset is small, the error approaches the SDS-TOF mode. In order to further reduce the error, the direct Kalman filter (KF) and the Unscented Kalman filter (UKF) are applied, finally the optimal method is selected for the actual test processes, and the effect is good.

This paper presents a method for the realization of hidden Wi-Fi auto-connect system based on android ROM-Level. Under this system, two Android devices can establish a Wi-Fi connection at a specific time, and do not display a Wi-Fi icon when the connection is successfully established. Among them, write the program of BroadcastReceiver in the Android framework layer to realize the control and management of Wi-Fi module, modify Android native calculator program to achieve user configuration function, and modify system application of SystemUI to realize the function of shielding Wi-Fi icon. Since the code is written based on the ROM-Level and the entire process is user-insensitive, the system maintains a high security and can provide new application scenarios.

When the heart sounds reach the chest wall surface through mediated tissue, it is prone to generate noise, which can reduce the accuracy of pathological diagnosis. A new denoising method for heart sound signal based on wavelet transform is proposed. First of all, the information signal is transformed by multi-scale wavelet. The wavelet coefficients of each scale indicate a distribution sequence of probability according to the corresponding wavelet entropy threshold to find the maximum entropy of wavelet on certain interval, and the interval is recognized as the leading range of noise. And then, a fixed threshold denoising method is used to adaptively enhance the judgment about absolute value with larger attenuation wavelet coefficients, which can reduce the high frequency sound signal loss and improve the heart sound signal to noise ratio. The denoising simulation experiment is carried out to test the performance. The result shows that the proposed method can improve the output signal to noise ratio of heart sound signal, reducing the influence of noise on the extraction of heart sound signal, and therefore, the noise elimination algorithm has stronger anti-interference ability and superior performance.
