Arbitrary-dimensional frequency estimation of complex sinusoid signals
Zhang Zhan · Wuhan University Journal of Natural Sciences · 1997
The problem of increasing computation in pace with the growth of dimension is discussed for arbitrary-dimensional frequency estimation of complex sinusoid signals. The conception of matrix core, the form of which doesn't change with dimension, is put forward. The deduced estimation formula shows that a N-dimensional frequency estimation could be obtained by N one-dimensional calculations. Obviously, while dimension increases, this method could reduce much computation.
