Abstract
Numerically stable closed form expressions for the solution of the total least squares (TLS) problem with linear equality constraints (LCTLS) are derived. A constrained subspace linear predictive frequency estimation technique called LCTLS-linear predictive (LCTLS-LP) is proposed. The method is suited for scenarios where the presence of a known frequency component makes it difficult to resolve a closely spaced component
