5203 |a"The frequency-independent strong-signal suppressor (FISSS) uses nonlinear processing plus cancellation techniques to provide substantial interference suppression. However, only laboratory proof of its operation existed. Although considerable effort went into trying to determine the principle of operation, this principle was not found. In this report, some analytical and simulation attacks on this problem are described. Extensive laboratory measurements were made on devices operating at 1.5 GHz and 10 GHz. The 10 GHz device was combined with direct-sequence spread spectrum, and had measured processing gains of about 12 dB against CW and frequency-modulated single tones. The experimental highlight was the successful suppression of noise interference of between 6 and 12 dB, depending upon the noise bandwidth"--Abstract, page iii.
