Spatial - Temporal Signal Processing

Among multi-access communications techniques, CDMA (Code Division Multiple Access) is interference-limited. Conventional single-user receivers su er from the nearfar problem in CDMA cellular communications systems. One method to suppress multi-access interference is digital beamforming by using base-station antenna arrays. However, using beamforming alone cannot solve the near-far problem. Verd...

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...

Spatial limitation of vertical-size disparity processing

We investigated the upper limit of horizontal spatial modulation of vertical-size disparity in a textured surface for the perception of depth. In Experiment 1 subjects matched the appearance of a surface with modulated horizontal-size disparity to that of a surface with modulated vertical-size disparity. In Experiment 2 we determined the threshold amplitude of modulation of vertical-size dispar...
