SNR estimation for multilevel constellations using higher-order moments
Abstract--The performance of existing moments-based nondata-aided (NDA) estimators of signal-to-noise ratio (SNR) in digital communication systems substantially degrades with multi...

A Doppler robust max-min approach to radar code design
Abstract--This correspondence considers the problem of robust waveform design in the presence of colored Gaussian disturbance under a similarity and an energy constraint. We resort...

A nondata-aided SNR estimation technique for multilevel modulations exploiting signal cyclostationarity
Signal-to-noise ratio (SNR) estimators of linear modulation schemes usually operate at one sample per symbol at the matched filter output. In this paper we propose a new method for...

Channel energy based estimation of target trajectories using distributed sensors with low communication rate
Abstract--Sensor localization using channel energy measurements of distributed sensors has been studied in various scenarios. However, it is usually assumed that the target does no...

Cyclic prefix based enhanced data recovery in OFDM
In this correspondence, we show how the cyclic prefix can be used to enhance the performance of an OFDM receiver. Specifically, we show how an OFDM symbol can be blindly detected ...

Algebraic signal processing theory: sampling for infinite and finite 1-D space
We derive a signal processing framework, called space signal processing, that parallels time signal processing. As such, it comes in four versions (continuous/discrete, infinite/fi...
