–Missile borne Monopulse receivers invariably track the target in three domains, namely frequency, range and angle. For effective jamming of these receivers, it is essential that breaking of the track should be achieved in at least two domains. In frequency domain, so long as the monopulse receiver locks onto the radar echo frequency, the radar tracks the target. When there is a disturbance int...

The effects of aberration on the Bit-Error-Rate (BER) and reliability of free- space optical (FSO) communication links are investigated. Based on aberrated divergent rectangular partially coherent flat-topped beam formula on the receiver plane and considering the atmosphere losses due to absorption and scattering, numerical values for Power In Bucket (PIB), Signal to Noise Ratio (SNR) and BER a...

Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of  non-homogeneity in RF receive and transmit. This can be the most effective source of error in  quantitative  studies  in  MRI  imaging.  Part  of  this  non-homogeneity  demonstrates  the  characteristics of RF coil and part of it is due to the interaction of RF field with the material being  imaged...

This paper describes a spread-spectrum downlink RAKE receiver that computes a data detection in the frequency domain. We assume a pilot signal is transmitted with data signals for channel sounding. The pilot signal does not degrade the receiver bit error rate (BER) performance because the receiver estimates the pilot signal and subtracts the estimated pilot signal from the received signal befor...

The performance of the quantum NeymanPearson receiver for a binary coherent state signal in the presence of thermal noise is numerically investigated. To see the detection sensitivity of the quantum Neyman-Pearson receiver, its receiver operating characteristics (ROC) are numerically obtained. The performance limit of the quantum Neyman-Pearson receiver is directly computed when the false alarm...

This paper presents an alternative approach for signal detection and equalization using the continuous wavelet transform (CWT) and the artificial neural network (ANN) in diffuse indoor optical wireless links (OWL). The wavelet analysis is used for signal pre-processing (feature extraction) and the ANN for signal detection. Traditional receiver architectures based on matched filter (MF) experien...
