Computationally efficient and robust frequency-domain GSC

In this paper, we propose a novel adaptive beamforming algorithm with low signal distortion capability and high computational efficiency. The proposed algorithm incorporates the crosstalk-resistant adaptive noise canceller (CTRANC) in place of the usual adaptive interference canceller (AIC). Doing so, a better signal leakage estimate is provided at the adaptive interference canceller input but ...

Theoretical Analysis of the General Transfer Function Gsc

In recent work we considered the use of a microphone array located in a reverberated room where general acoustic transfer functions (ATFs) relate the source signal and the microphones for enhancing a speech signal contaminated by interference. The resulting frequency-domain algorithm enables dealing with a complicated ATF in the same simple manner as Griffiths & Jim GSC algorithm deals with del...

Improving the Absolute Astrometry of HST Data with GSC-II

We have used the new GSC-II to significantly improve the absolute astrometric accuracy of a large number of ACS datasets from the first years of ACS operations, reducing the initial levels of uncertainty (typically 1 2”, or more in some cases) to an accuracy of about 0.1 0.3”. There are typically enough GSC-II objects in the field of view of the ACS/WFC detectors to enable a robust solution to ...

Joint Minimum Selection GSC and Down-Link Power Control

Abstract— We propose and analyze in this paper a new adaptive power controlled minimum selection generalized selection combining (MS-GSC) diversity scheme termed joint combining and power control (JCPC). The key idea is to meet the required quality of service while using the minimum possible transmit and processing power. Four power control variants accounting for practical implementation const...
