... VSS-SPAPA can achieve a lower steady-state misalignment than SPAPA, approximate 10 dB improvement was achieved. The steady- state misalignment of VSS-APA was the same as that of VSS- SPAPA, but ... approaches are only applicable to nonproportionate adaptive algorithms. In this article, we propose a variable step-size pro- portionate a ne projection algorithm (VSS-PAPA) for...

... is a mathematically derived approach. Beamforming uses spatially sampled data from an array of two or more sensors to estimate arrival angles and waveforms of “dominant” signals in the wavefield. ... distortions. For monaural CASA, the test data was exactly the same as that used in Section 6.1. For beamforming and CASA- EB, however, array data was simulated from the speech and interf...

... following, weproposeaclassofrealorthogonalgroupcodesforUWB signals based on Hadamard transform and rotation matrices, which also admit more general transmit antenna settings. For n = 2 m ,withm an integer, a Hadamard ... equal to 1. This design works well for any transmission rate R and M = 2 m transmit antennas. For odd values of M, a similar design can be applied for a few s...
