Mathematically, a coherent state is defined to be the (unique) eigenstate of the annihilation operator â with corresponding eigenvalue α. Formally, this reads, Since â is not hermitian, α is, in general, a complex number. Writing α and θ are called the amplitude and phase of the state . The state is called a canonical coherent state in the literature, since there are m… WebNote that the noise is complex, white and Gaussian distributed. If the received signal contains the target, it is given by. x = s + n; The matched filter in this case is trivial, since the signal itself is a unit sample. mf = 1; In …
