A Study of a Blind "Adaptive" Algorithm in the Time and Frequency Domain
Ilir F. Progri, William R. Michalson, Matthew C. Bromberg · 2002
A phased antenna array employing a blind adaptive algorithm can be exploited to extract signals with unknown characteristics coming from unknown locations based only on very limited knowledge of the received signal properties. These signals may be sources of interference to a desired GPS signal and whose locations might be determined once these signals are extracted. In this paper we present the advantages and disadvantages of exploiting a blind adaptive algorithm both in the time and frequency domains. Simulation results illustrate the performance of the blind algorithm by comparing the extracted signals with the original signals and the estimated signal locations with the corresponding actual signal locations.
