Analysis of efficiency and quality of filters suppressing RFI in radio detection of cosmic rays
Original language description
Radio stations of the Auger Engineering Radio Array (AERA) investigates radio signals from coherent emissions due to geomagnetic radiation and charge excess processes. The frequency band is limited to 30-80 MHz. In order to improve the signal to noise ratio, RFI filters have to be used to suppress this contamination. The paper compares several (currently in use and proposed) RFI filters. We analyzed: the non-adaptive filter (IIR notch) as well as adaptive filters: IIR notch supported by the virtual NIOS (R) processor, FIR based on the linear prediction supported by the virtual NIOS (R) processor and finally the Least Mean Square filter. The LMS filter proposed for the RFI suppression should use correct learning factor, crucial for a stability of the filter, which could be determined by eigenvalues of the auto-correlation matrix built for ADC samples.
