This paper deals with the hardware implementation of base band (acquisition and tracking) modules of a GPS receiver using system generator 9.2 has been tried out. The implementation will be tested on Lyrtech (small form factor-software defined radio) platform which consists of 3 layers. The upper layer is the radio frequency (1 GHz) layer, middle layer is the ADACMasterIII layer and the last is...

This paper deals with digital base band signal processing algorithms, which are seen as enabling technologies for software-enabled radios, that are intended for the correction of the analog front end. In particular, this paper focuses on the design, optimization and testability of predistortion functions suitable for the linearization of narrowband and wideband transmitters developed with a hyb...

In this paper, we present techniques for mitigating the Negative Bias Temperature Instability (NBTI) effect on extensible processors. Firstly, the effect of NBTI on the extended instruction set architecture and the arithmetic logic unit of extensible processors is studied. The study includes modeling the circuit delay increase due to the NBTI and analyzing its impact on the processor lifetime. ...

languages to coexist within a single computer system. Here the term "language" is understood to include a particular data base. New languages may be defined by constructing a new base language with its syntax and semantics, by extending the terminology from a given base level in order to reflect specific concepts, or by associating a given base language with a certain data base. REL consists of...

A selected solid complex of the Schiff base ligand derived from Glutaric anhydride with Cu(II) ion was synthesized and characterized by FT-IR, Electronic, ESR Spectral Analyses, Magnetic susceptibility and Molar Conductance Measurements. The disappearance of ν(O-H) hydroxyl band of the phenolic and the lowering shift of the stretching frequency of the ν(CH=N) azomethine band in the ligand after...

We present a programmable continuous-time floating-gate Fourier processor that decomposes the incoming signal into frequency bands by analog bandpass filters, multiplies each channel by a nonvolitile weight, and then recombines the frequency channels. A digital signal processor would take a similar approach of computing a fast Fourier transform (FFT), multiplying the frequency components by a w...

The new wireless communication standard UMTS applies an advanced dual-mode channel coding scheme. In this contribution we investigate the feasibility of implementing the algorithm on a digital signal processor device and the implication upon the processor architecture. Starting with a base architecture which allows for scalability and customization we derive new system parameters and compare th...
