Robust optimal systems in radar and communications
Abstract
The design of robust systems and optimization of signals and processors under arbitrary noise conditions is considered. The robustness of performance, i.e., stability of the power of the test, is brought about by using the generalized quantile detector of which the m-Interval detector and the rank detectors are subsets. The analysis is carried out by using the discrete maximum principle and constraints are applied on the transmitter power, the receiver power, intersymbol interference, timing jitter and Gabor bandwidth. The resulting nonlinear two-point boundary-value equations are solved on a digital computer by the method of adjoints. For communications over channels with low signal-to-noise conditions and for efficient utilization of bandwidth, methods are presented to construct higher order alphabets.
