Scalar ambiguity
Webscalar ambiguity problem is resolved by assigning a pre-determined value to one of the element of s [15]. That is, a constraint function f(θ),sn − c =0is put on the parameter θ, where sn denotes the nth element of s and c is some pre-determined constant. This is exactly the third approach mentioned above. WebIf N T = 1, then the ambiguity becomes a scalar, which can be further removed by using one or few pilot symbols. However, if N T ≥ 2, then resolving the unknown matrix ambiguity is a...
