In particular, the minimum variance linear filtering problems incorporating quantum mechanical measurements is solved for both scalar and vector signal processes. The simplification of the filter under certain assumptions is demonstrated. Examples from optical communication systems illustrate the result.},

	abstract = {Recent results on the analysis of models and structural properties of linear distributed systems are presented. The presentation emphasizes the role play-ed by harmonic analysis in these studies. The conclusions are that a careful selection of mathematical methods makes possible a satisfactory classification and detailed analysis of distributed systems models. These methods provide simple models that reflect input-output data of engineering importance.},

	author = {Baras, John S., Harger, Robert O.},
	year = {1975},
	month = {04/1975},
	abstract = {We analyze here the problem of estimating a member of a vector discrete time process utilizing past and present quantum mechanical~measurements. The minimum variance linear estimator based on optimal present measure-ment selection combined with an optimal linear processing of past measurements is studied. A necessary condition for the optimal extended measurement and the optimal coefficient matri-ces is given which leads to the generation of several more specialized necessary conditions. Certain operator equations related to these necessary conditions are studied and it is found that the conditions are necessary and sufficient in the commutative case. Finally when the average quantum measurement is linear in the random signal and the signal process is pairwise Gaussian, the filter separates: the optimal measurement can be taken the same as the optimal measurement with no regard to past data and the past and present data are processed classically. The results are illustrated by considering the estimator of the amplitude and phase of a laser received in a single-mode ca-vity along with thermal noise; when the random signal sequence satisfies a linear recursion, the estimate can be computed recursively.},
