WebTo remove the scalar ambiguity in conventional blind channel estimation algorithms, totally blind channel estimation (TBCE) is proposed by using multiple constellations. To estimate the unknown scalar, its phase is decomposed into a fractional phase and an integer phase. However, the maximum-likelihood (ML) algorithm for the fractional phase does not have … WebDec 1, 2024 · We now study the concept of scalar ambiguity, scalar freeness and vector ambiguity for a bounded language of matrices, showing that these problems are …
WebNov 1, 2024 · Then, the symmetric matrices Q 1 and R 11 can be identified up to a scalar ambiguity if the graph pattern (Bullo, 2024) represented by the non-zero entries of U T Q 1 U or U − 1 B 1 R 1 − 1 B 1 T U − T contains a circle covering all the graph nodes. Proof. By Lemma 4, the identifiability can be analyzed according to (39) or (42). WebIn physics, canonical quantization is a procedure for quantizing a classical theory, while attempting to preserve the formal structure, such as symmetries, of the classical theory, to the greatest extent possible. Historically, this was not quite Werner Heisenberg 's route to obtaining quantum mechanics, but Paul Dirac introduced it in his 1926 ...
