Abstract :
This paper presents a new method for the detection of amplitude modulation on unknown, low signal-to-noise ratio signals in additive, white Gaussian noise. The robustness of the new technique is addressed with simulations in Rayleigh distributed noise and the effect of quantisation of the unknown signal is also explored. The performance of the new method is compared to a technique currently employed in an operational signal classification system
