The paper explores the manner in which an organization's data and information can be effectively utilized to assist an organization to achieve its business objectives. With the increased popularity of data warehousing and executive information systems, there is renewed interest by IT practitioners in data models and database structures, in particular(More)
This paper proposes a novel method to improve the utilization efficiency and performance of field-programmable gate arrays (FPGAs). The proposed method, ExorBDD, uses a stage of exclusive-sum-of-product (ESOP) minimization, followed by a stage of decomposition using binary decision diagrams (BDDs). For exclusive OR (XOR)–intensive circuits, experiments were(More)
QAM based communications systems suffer performance loss due to the practical implementation of the matched filter in the receiver. The practical matched filter causes two types of interference: Intersymbol Interference and Adjacent Channel Interference. The combined effect of the interference is minimized by applying a tapered window to the matched filter(More)
The computer programs which control autonomous mobile robots can make use of fuzzy processing and computing with words in order to extend their capabilities by allowing them to be less literal and exact match oriented. Both sensor data interpretation and planned activities subtleties benefit from fuzzy inexact processing.[1] The sciences of astronomy and(More)
Pilot symbol assisted modulation (PSAM) is a method to compensate for fading in wireless mobile communications. Known pilot symbols are periodically inserted into the data symbol stream and the receiver uses these symbols to derive the amplitude and phase reference required to set decision thresholds. In mobile communication, PSAM can facilitate the use of(More)
