Because of the poor observability of Inertial Navigation System on stationary base, the estimation error of the azimuth will converge very slowly in initial alignment by means of Kalmari filtering, and making the time initial alignment is longer. In this paper, a fast estimation method of the azimuth error is creatively proposed for the initial alignment of INS on stationary base. On the Basis of the the fast convergence of the leveling error, the azimuth error can be directly calculated. By means of this fast initial alignment method, the time of initial alignment is reduced greatly. The computer simulation results illustrate the efficiency of the method.

A Module-based Wireless Node (MW-Node) is a Node with wireless and mobile capabilities added by means of modules. It is not a new node object derived from Node. Rather it is a new layout of mostly existing components. Rationale for this new design has been presented in [1]. The MW-Node provides a flexible support for wireless and mobile networking and in particular: support for multiple interfaces/multiple channels, and a common Basis for the implementation of wireless routing protocols.

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors also provide an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. These DSP families also provide a highly specialized instruction set, which is the Basis of the operational flexibility and speed of these DSPs.

C280x C/C++ Header Files and Peripheral Examples The DSP28xx C/C++ peripheral header files and example projects files facilitate writing C/C++ Code for the TI鈥檚 28xx MCUs. The code can be used as a learning tool or as the Basis for a development platform depending on the current needs of the user. We suggest that you immediately download these header files in order for an easier transition to understanding the 28xx peripherals.

Abstract—We describe a technique for image encoding in which local operators of many scales but identical shape serve as the Basis functions. The representation differs from established techniques in that the code elements are localized in spatial frequency as well as in space.

Abstract—The contourlet transform is a new two-dimensional extension of the wavelet transform using multiscale and direc- tional fi lter banks. The contourlet expansion is composed of Basis images oriented at various directions in multiple scales, with fl exible aspect ratios. Given this rich set of Basis images, the contourlet transform effectively captures smooth contours that are the dominant feature in natural images.
