Ambiguity function and Cramér-Rao bounds for universal mobile telecommunications system-based passive coherent location systems

, 2012
The concerns are with the calculation of monostatic and bistatic ambiguity function (AF) of a quadrature phase shift keying (QPSK) signal where the pulses are shaped with a root raised cosine (RRC) filter. The monostatic and bistatic modified Cramér-Rao
