Wideband DTV passive ISAR system design
Advanced operational modes for passive radar, including inverse synthetic aperture radar (ISAR), require particular consideration with respect to the receiver hardware. The spatial and spectral diversity of passive illuminators necessitates…
Effects of FDMA/TDMA Orthogonality on the Gaussian Pulse Train MIMO Ambiguity Function
As multiple-input multiple-output (MIMO) radar gains popularity, more efficient and better-performing detection algorithms are developed to exploit the benefits of having more transmitters and receivers. Many of these algorithms are…
Modeling and Simulation of Low-Frequency Noise in Nano Devices: Stochastically Correct and Carefully Crafted Numerical Techniques
Defects or traps in semiconductors and nano devices that randomly capture and emit charge carriers result in low-frequency noise, such as burst and 1/f noise, which are important concerns in…
Classification performance using ‘RF-DNA’ fingerprinting of ultra-wideband noise waveforms
Device classification is important in many applications such as industrial quality control, through-wall imaging and network security. A novel approach has been proposed to use a digital noise radar (DNR) to actively…
A 9-bit body-biased vernier ring time-to-digital converter in 65 nm CMOS technology
A high resolution Vernier Ring Time-to-digital Converter is presented in this paper. Body bias is applied to its delay cells to obtain a finer delay difference between two delay chains. The…
Frequency offset estimation of the linear mixture of two co-frequency 8 phase-shift keying modulated signals
A frequency offset estimation (FOE) algorithm based on the maximum-likelihood criterion is proposed for the linear mixture of two 8PSK modulated signals with fixed frame length and frame synchronisation code on the…
Families of multi-dimensional arrays with optimal correlations between all members
Families of sequences with low off-peak autocorrelation and low cross-correlation are highly valued in spread-spectrum communication. Digital watermarking has an equal need for diverse families of orthogonal multi-dimensional (nD) arrays, where each…
Kalman filter based motion estimation algorithm using energy model
Digital video signal compression is an important requirement for multimedia systems. It can be performed by block-based motion estimation algorithms, which eventuate into acceptable outcomes in both the compression and quality. Already adaptive…
Modified SLM method for reduction of PAPR in OFDM systems using decimal sequences
Orthogonal frequency division multiplexing (OFDM) is an attractive current technology to achieve high data rate in wireless communication systems. One of the main drawback associated with the OFDM is high…
