According to the shortcomings of large volume and high cost about the plate recognition system, an embedded plate recognition system is developed based on the ARM11 processor at lower costs. Taking the embedded Linux system as the software development platform, the system uses graphical user interface to operate and control the machine. Using CMOS camera system as image acquisition device, the system adopts HSV algorithm to realize the image classification on the platform of the embedded plate recognition system. The experimental results show that the embedded system runs stably, can realize the plate classification by color, and has the advantages of small size, low power consumption, convenience for using and so on. The embedded system provides a new thought for plate recognition.

U-boot is an open source project under the protocol of GPL, which has been widely used as boot application on embedded system. Normally, U-boot initializes hardware and send to hardware information to the embedded OS. In mobile thermals, especially in the arm-based mobile device, U-boot has played an important role. U-boot supports many kinds of development boards. However it does not support every board, so it needs to be modified to fit other board. This paper analyses the boot procedure and the source code of U-boot, studies how to add a custom command on U-boot source, analyses the protocol of USB, then gives us a new way to download the binary U-boot file or the kernel directly to RAM and run. In this way, we do not need to burn the binary U-boot file or the kernel to Flash. This has save a lot of time in embedded system development.

Since the boot code locates in the bottom of embedded system, so the design of boot code is the key technology and the important steps of system development during the development process of embedded system. Although the boot code supporting new framework has been updating, the boot code of manufacturer giving is an old version of a few years ago in the current market popular embedded products. So this paper analyzes the U-boot code commonly used and in the popular in detail, combining with the startup process of embedded Linux system, then, this paper gives a process, transplanting the new version of U-boot code using the UT6410 as development platform. On the basis of completing the basic function transplantation, this paper adds the network card and DNW. Experiments show that the new version of transplantation can run smoothly, and improve the efficiency of the system.

The paper presents the development of a multifunctional flight display system for light-sport aircraft flying. The requirements and design of the system is discussed. It is mainly designed as a backup system for flying rather than a certified flight instrument. An ARM-core embedded system is chosen as the development platform with Linux operation system. The system basically takes advantage of 3-D positioning information from GPS which has been widely used on general aviation aircraft. Its diverse interfaces provide system redundancy with wired or wireless connection to external sensor systems for aircraft attitude, pressure height, and magnetic heading. The proposed flight display system has been developed and running over the embedded system.

The Embedded System

By increasing the demand for radio frequency (RF) and access of hackers and spoofers to low price hardware and software defined radios (SDR), radio frequency interference (RFI) became a more frequent and serious problem. In order to increase the security of satellite communication (Satcom) and guarantee the quality of service (QoS) of end users, it is crucial to detect the RFI in the desired bandwidth and protect the receiver with a proper mitigation mechanism. Digital narrowband signals are so sensitive into the interference and because of their special power spectrum shape, it is hard to detect and eliminate the RFI from their bandwidth. Thus, a proper detector requires a high precision and smooth estimation of input signal power spectral density (PSD). By utilizing the presented power spectrum by the simplified Welch method, this article proposes a solid and effective algorithm that can find all necessary interference parameters in the frequency domain while targeting practical implantation for the embedded system with minimum complexity. The proposed detector can detect several multi narrowband interferences and estimate their center frequency, bandwidth, power, start, and end of each interference individually. To remove multiple interferences, a chain of several infinite impulse response (IIR) notch filters with multiplexers is proposed. To minimize damage to the original signal, the bandwidth of each notch is adjusted in a way that maximizes the received signal to noise ratio (SNR) by the receiver. Multiple carrier wave interferences (MCWI) is utilized as a jamming attack to the Digital Video Broadcasting-Satellite-Second Generation (DVB-S2) receiver and performance of a new detector and mitigation system is investigated and validated in both simulation and practical tests. Based on the obtained results, the proposed detector can detect a weak power interference down to −25 dB and track a hopping frequency interference with center frequency variation speed up to 3 kHz. Bit error ratio (BER) performance shows 3 dB improvement by utilizing new adaptive mitigation scenario compared to non-adaptive one. Finally, the protected DVB-S2 can receive the data with SNR close to the normal situation while it is under the attack of the MCWI jammer.
