Wireless Data Transmission

Based on UDP protocol in Visual Basic Winsock control, this paper designed third-party software to send and receive data. Wireless data transmission module used CM3160EP module. In order to decrease wireless data loss rate, four kinds of packets format is designed. The results show the stable data transmission and verify the send-receive and display of hexadecimal data on server-side.

Set Up

It discusses the reasons of the data transmission time delay and packets loss based on the theory of net data transmission. Aimed to the question of the time delay of data transmission and packets loss, the control system models are set up to analyze their influence to the performance of the control system. Based on the synchronous control model analysis with wireless data transmission, a method to control the system is reached with the state prediction when the communication error or data loss appears. It can control constantly when communication errors appear, and also it can get the most error period by numerical analysis.

Cognitive Radio Technology

Cognitive radio technology has received wide attention for its ability to sense and use idle frequency. IEEE 802.22 WRAN, the first to follow the standard in cognitive radio technology, is featured by spectrum sensing and wireless data transmission. As far as wireless transmission is concerned, the availability and implementation of a mature and robust physical layer algorithm are essential to high performance. For the physical layer of WRAN using OFDMA technology, this paper proposes a synchronization algorithm and at the same time provides a public platform for the improvement and verification of that new algorithm. The simulation results show that the performance of the platform is highly close to the theoretical value.

Electronic Measurement

Signal monitoring and waveform analysis play a significant role in state-of-the-art signal processing and electronic measurement. Traditional oscilloscopes tend to be heavy and huge, which makes it impossible for outdoor signal measurement. In addition, most of those oscilloscopes can measure merely two signals simultaneously. This article proposes the design of multi-channel digital oscilloscope over common Android mobile device. In our system we use STM32 development board to implement up to eight input channels, data processing and wireless transmission. In addition, an Android application is designed for Wi-Fi data reception, respective waveform demonstration and derivation of each signal’s amplitude and frequency. In order to transmit up to eight digital signals simultaneously as fast as possible, we designed an algorithm where all signals’ data can be transmitted within a surprisingly small amount of wireless data. In our system test, wireless data transmission is implemented and each waveform can be recovered and demonstrated basically.
