Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...

This paper studies the design requirements and challenges of SDR (Software-Defined Radio) vector processors for 5G micro base stations. Pareto principle reflects rule "vital few trivial many", which states that 80% consequences stem from 20% causes. Since instructions account about running time station processor, it is essential to speed up as complex operations consuming most runtime. proposes...

This paper presents a verification processor, developed under ESA contract, for the generation of polarimetric, interferometric and polarimetric-interferometric geocoded products derived from SAR data obtained from the ALOS PALSAR instrument. The processor, developed with a modular approach, contains the following main elements: Phase-preserving fine resolution processor; Phase-preserving ScanS...

This paper presents a universal hardware platform (UHP) based on software defined radio (SDR) technology and developed to accelerate the prototyping testing new algorithmic solutions for modern systems. There are two integrated transceivers baseband processor board. Thus, four complete RF transmitting receiving channels, with observation paths transmitted signals monitoring could be supported. ...

This paper describes a NL data base interface which consists oF two parts: a Natural Language Processor (NLP) and a data base application program (DBAP). The NLP is a general pur!~se language processor which builds a formal representation of the meaning of the English utterances it is given. The DBAP is an algorithm with builds a query in a augmented relational algebra from the output of the NL...

This paper is concerned with the stochastic modeling of processor scheduling and of queuing due to contention for resources in data base management systems. The processing services rendered in searching the data base and retrieving and processing information are modeled explicitly, as is the algorithm used to schedule these services on the processor. The scheduling of the processor is based on ...
