Signal detection in non-stationary broadband noise

[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991
An algorithm for signal detection across a wide band of frequencies in which the noise statistics may be considered stationary only over very short intervals is proposed. The algorithm estimates the noise level in each channel of a channelized receiver, based on the levels in the quietest channels, after compensating for time-varying passband ripple ...

On the detection of random broadband signals

International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2012
One of the most critical problems in immunity testing is to detect the malfunctions of the equipment under test (EUT) when the susceptibility signals are injected into it. In most EMC specifications it is left to the test operator to decide whether the EUT is susceptible on the basis of examination of qualitative output parameters; even if quantitative

Ideal amplification of broadband signals

International Journal of Microwave and Wireless Technologies, 2013
This paper describes a digital signal processing (DSP) method for achieving “ideal” amplification, maximizing both the average output signal power and power-added-efficiency for any signal waveform and any power amplifier (PA) transfer characteristic. Detailed algorithms are described for optimally accomplishing peak reduction (PR), predistortion (PD ...

Worst-case signal spectra for broadband detection

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1985
As a class, broadband detection problems are difficult to analyze because, even for a fixed noise spectrum and fixed broadband signal-to-noise ratio (SNR), a continuum of different signal spectrum choices exists, each resulting in a different receiver operating characteristic (ROC) point. This paper derives the asymptotically worst-case signal spectrum
