Robust Waveform Design.
Abstract
Detectors and estimators which utilize signals in the high frequency band (HF) as input data usually suffer from performance deterioration as a result of the presence of high frequency interference. This interference can be categorized as either intelligent or non-intelligent. The non-intelligent interference occurs mainly as the result of channel noise, which is primarily inpulsive in nature in the HF band (atmospheric and man-made noise) and should be accounted for during the receiver design stage. The intelligent interference is developed by another user either involuntarily when he utilizes the same channel, or deliberately to degrade the receiver performance. The second type of interference in general has a more deleterious affect on the receiver performance than the first and should be taken into account in the process of signal design. the classical approach for solving this problem is either to design a receiver and to choose the signal which is optimal for a channel model developed apriori from channel measurements, or to utilize an adaptive technique which works for a finite-dimensional class of channel models.
