A generalized approach to direction finding
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1986With reference to the recently developed estimation of signal parameters using a rotational invariance techniques (ESPRIT) it is pointed out that other operators can be used to generate the matrix pencil. By way of example, the moving window operator is discussed. >

Direction finding with a rotating antenna
2012 20th Signal Processing and Communications Applications Conference (SIU), 2012Finding the direction of the emitters is a problem to be solved in many areas. One of the methods used for that purpose is that using a rotating directional antenna and obtaining the direction estimate by processing the measured signal amplitudes. Direction estimation, in principle, is based on the own antenna pattern modulation on the measured signal.

Consider a digraph with n vertices. For any fixed value k , we present linear- and almost-linear-time algorithms to find a cycle of length ≥ k , if one exists. We also find a cycle that has length ≥ log n /log log n in ...
