Cramer-Rao Bounds for Signal-to-Noise Ratio and Combiner Weight Estimation
Samuel J. Dolinar · NASA Technical Reports Server (NASA) · 1986
Cramer-Rao lower bounds on estimator variance are calculated for arbitrary unbiased estimates of signal-to-noise ratio and combiner weight parameters. Estimates are assumed to be based on a discrete set of observables obtained by matched filtering of a biphase modulated signal. The bounds are developed first for a problem model based on one observable per channel symbol period, and then extended to a more general problem in which subperiod observables are also available.
