NettetGiven a linear model, we address two problems: (1) the problem of estimating the parameters and (2) the problem of verifying the parameter estimates. We show that with additive Gaussian measurement noise the maximum likelihood estimates of the parameters are given by solving an integer least-squares problem. NettetThis is a nonstandard least-squares problem, due to the integer constraints on the ambiguities. This type of least-squares problem was first introduced in [Teunissen, 1993] and has been coined with the term ‘integer least-squares’. Conceptually one can divide the computation of Eq. (2.2) into three different steps. In the first step one simply

NettetIt is shown that the integer least-squares principle maximizes the probability of correct integer estimation. Sharp and easy-tocompute bounds are given for both the ambiguity success rate and the baseline’s probability of concentration. Keywords.

The performance of the method will be discussed, and although it is stressed that the method is generally applicable, attention is restricted to short-baseline applications in the present contribution. tarenzi ks toolsNettetIn this contribution a new method is introduced that enables very fast integer least-squares estimation of the ambiguities. The method makes use of an ambiguity transformation that allows one to reformulate the original ambiguity estimation problem as a new problem that is much easier to solve. climatizacion josbalsa slNettetRecently, there has been a growing research interest in integer parameter estimation in linear models due to its ap- plication in the global positioning system (GPS), which is a navigation system that enables quick, accurate, and in- expensive positioning anywhere on the globe at any time. climatizacion ekokaiNettetsquares In this case, the integer least-squares estimates of the ambiguities are found by means of a simple rounding of the least-min (8) a i (aˆ i a 1)2/σ2 1 (aˆ m a m)2/σ2 m, with a i ∈Z squares estimates to their nearest integer.
