Spatial Processing for Frequency Diversity Schemes - Signal Processing, IEEE Transactions on

A novel technique to obtain optimum blind spatial processing for frequency diversity spread spectrum (FDSS) communication systems is introduced. The sufficient statistics for a linear combiner, which prove ineffective due to the interferers frequency characteristics, are modified to yield improved detection under partial jamming in the spectral domain. Robustness to partial time jamming is achi...

Acoustic Communication Using Time-Reversal Signal Processing: Spatial and Frequency Diversity

Time-reversal signal processing can be viewed as a form of matched filtering that operates both in time and in space. Acoustic communication represents a promising potential application of the processing. In designing a communications system, constraints are imposed by the available bandwidth and by the geometry of the time-reversal array. In the present paper, the interplay between bandwidth a...

Expectancy effects on spatial frequency processing

We explored top-down modulation of spatial frequency (SF) processing. When auditory pre-cueing directed observers' attention to one of two 4-octaves (SF) apart plaid components observers tended to perceive the cued component, suggesting selective attention to the SF channel they expected to carry task relevant information. In agreement, pre-cueing had no effect with components often processed b...

Study of Spatial Diversity Schemes in Multiple Antenna Systems

One of the most common problems faced by designers of wireless communication systems is the spatiotemporal variations in the wireless channel which arise mainly due to the phenomenon of multipath fading which is inevitable in scattering environments that are subject to changes over time. A wide variety of pre/post processing techniques have been used to mitigate the degrading effects of such ch...

Spatial frequency domain image processing for biometric recognition

Biometric recognition refers to the process of matching an input biometric to stored biometric information. In particular, biometric verification refers to matching the live biometric input from an individual to the stored biometric template about that individual. Examples of biometrics include face images, fingerprint images, iris images, retinal scans, etc. Thus, image processing techniques p...
