Blanking Of TDMA Interference And Its Effect On Radio-astronomical Correlation Measurements: Experimental Results
نویسندگان
چکیده
The fast growth of the wireless communication industry poses severe limitations on radio astronomical observations. Two such examples are the Iridium system which will probably cause problems within bands reserved to radio astronomy and the GSM system which became ubiquitous and thus prevents observation in its band. In this paper we present the results of blanking of interfering signals measured at the Westerbork Synthesis Radio Telescope. Keywords— Interference rejection, signal detection, radio-astronomical receivers.

The effect of blanking of TDMA interference on radio-astronomical correlation measurements
Radio astronomical observations are increasingly contaminated by man-made communication signals. TDMA signals such as GSM can be suppressed in the time domain by inhibiting the correlation process when the interfering signal is present. In this paper we propose a spectral-temporal detection and blanking scheme applicable to array radiotelescopes. The effectiveness is demonstrated through simula...
متن کاملThe effect of blanking of TDMA interference on radio-astronomical observations: experimental results
The fast growth of the wireless communication industry poses severe limitations on radio astronomical observations. This is largely due to the fact that in radio astronomy, in contrast to communication systems, the signals of interest are many orders of magnitude below the receiver noise power levels. The structure of some communication signals opens the possibility to reduce the effect on radi...
متن کاملDetection and Blanking of Gsm Interference in Radio-astronomical Observations
Radio-astronomical observations are increasingly disturbed by man-made communication signals, satellite and broadcast services. In particular, the GSM band is a highly saturated domain, full with interferers which are much stronger than radio astronomical signals. In this paper we propose a strategy to reduce this interference using its non-stationary nature. We describe a multichannel interfer...

متن کاملMitigation of Continuous Interference in Radio Astronomy Using Spatial Filtering
The contamination of radio astronomical measurements by man-made Radio Frequency Interference (RFI) is becoming an increasingly serious problem and therefore the application of interference mitigation techniques is essential. Most current techniques address impulsive or intermittent interference and are based on time-frequency detection and blanking. Continually present interferers cannot be cu...
