A measurement matrix plays an important role in the compressed sensing theory for sparse spatial spectral estimation. However, the RIP theory cannot provide a best measurement matrix for all the applications. In general, different measurement matrices have different characteristics to suit for different applications. Thus, this paper mainly researches on six common measurement matrices. Different...
While Histograms of Gradients (HOG) has been proven as an excellent feature set for human detection, its intricate computation does not readily lend itself to be realized into high performance and economical hardware. This paper proposes several methods to simplify complicated computations of HOG, so that HOG feature extraction can be speeded up, which is essential in real-time applications, and become...
Distributed interactive applications (DIAs) such as online gaming have attracted a vast number of users over the Internet. It is however known that the deployment of DIA systems comes with peculiar hardware/software requirements on the users' consoles. Recently, such industrial pioneers as Gaikai, Onlive and Ciinow have offered a new based distributed interactive applications generation of cloud (CDIAs),...
When GeForce256 was issued in 1999, NVIDIA first proposes the concept of GPU (Graphics Processor Unit), and then a large number of complex application requirements make the whole industry flourishing. This paper first presents the development of GPU, and then briefly introduces and compares two popular development platform of GPU: CUDA (Compute Unified Device Architecture) C and OpenCL (Open Computing...
Wireless meter reading based on a combination of WIA wireless network technology and 4G wireless network technology is proposed. Data can be collected and transferred to the background processing center timely and accurate. The article describes WIA wireless network hardware design and software design process. Greatly saving cost of laying communication lines due to using the wireless communication...
RFID application becomes the focus recently. As an automatic identification technology, RFID has many advantages over traditional one like barcode. It does bring about tremendous changes, and also face lots of barriers during investment. In this paper, we integrate technology risk, IT risk and RFID risk, develop a RFID risk factor framework with analogy method, and find out the relationship between...
For the practical application of synchronous acquisition of digital signals on many kinds of circuit boards, this paper, based on NI-TCLK (Trigger clock) synchronization technology, the modular hardware as the circuit board based on PXI (PCI extensions for Instrumentation) bus, as well as the modular software as NI-LABVIEW, a multi-module synchronic data acquisition system is developed. Accordingly,...
For more and more data services in GPRS networks, through analysis of both the GPRS network structure and the data features of Gb port, introducing into the analysis flow of multi-level, analysis and research the network data from the bottom-up.
This paper presents a high speed Radix-8 Log-MAP turbo decoder recursion architecture: algorithmic approximation and architectural optimization are incorporated in the proposed designs to reduce the critical path. The synthesis results show that the proposed design has a high throughput of 693 Mbps in 0.18 um CMOS technology, which is nearly 3 times higher than using conventional Radix-2 architecture...
