Abstract
In this paper, we describe a real-valued parameterization for IQML or MODE algorithms. The cisoid time series or array snapshot is transformed such that real and imaginary parts of the data vector have the same subspace structure. This transformation is identical to those used in unitary ESPRIT. A representation for this subspace and its orthogonal subspace are defined. It is also shown that the non-triviality constraint in these algorithms is quadratic.
