Abstract

Real-time implementation of electronic warfare digital receivers is strongly constrained by the limited operation rate of data processing blocks. This problem can be partially overcome by using monobit DFT instead of conventional DFT algorithm. The main disadvantage of monobit approximation lies on the increase of false alarm probability (PFA). In this paper an alternative data processing block based on a filter bank is proposed. This is achieved by means of a genetic algorithm optimization of the monobit DFT filter bank. Detection probability - false alarm probability performance (PD-PFA) of digital receiver by using the optimized filter bank is also discussed.

Bios

Roberto Gomez-Garcia was born in Madrid on 15th of October in 1977. He received the Telecommunications Engineering degree (equivalent to MSEE degree) from Polytechnical University of Madrid (UPM), Madrid, Spain, in 2001. Since October 2000 he has been part of the Microwave and Radar Group at the Signals, Systems and Radiocommunications Department(SSR), UPM, where he carried out his Master thesis on the design of microwave channelized active filters. Since October 2001, he has been working toward the Ph.D. degree on the analysis and design of novel tunable and active microwave bandpass filter configurations at the SSR. His research activities are in the area of high frequency circuit design for communication and radar systems.

Dr. Mateo Burgos-Garcia - Universidad Politecnica de Madrid

Mateo Burgos-Garcia was born in Segovia on 29th of April in 1964. He obtained his degree in Telecommunications Engineering in 1994, and PhD degree in 1989, both by the Polytechnical University of Madrid. Since 1989 he is member of the Microwaves and Radar Group (GMR) of the Telecommunications Engineering Technical School, at the Polytechnical University of Madrid. He is also professor at this University since 1991, in the general knowledge area of Signal Theory and Communications. His present research activities include digital receivers and the associated signal processing for radar and spectrum surveillance applications, and the development of advanced base stations for wireless applications both in L band (DECT) and in millimetrewave frequencies (LMDS). Other topics of work are adaptive antennas, Low Probability of Interception radar and communications systems and telecommunications infrastructures for future homes.
