WebAfter obtaining the channel estimates at the receiver, the transmitted symbols are detected by using maximum likelihood (ML) detection. In order to achieve high data rates and better system performance we extend the single input single output (SISO) system to multiuser/multi input multi output (MIMO). Websymbols . We also have the index subset of OFF-state symbols. Ignoring in-tersymbol interference (ISI), the receiver would only receive signal light when the ON-state is transmitted. The joint distribu-tion of the signal intensity of ON-state symbols is [10] (17) where the th ON-state symbol intensity [6], [7] (18) Here, can be modeled as a ...

WebMaximum likelihood (ML) symbol detection method gives the best performance but because of its high complexity it can’t be used. Sphere decoder reduces the complexity to some extent providing similar performance as ML estimate. The other methods used are Zero forcing and Minimum mean square estimation (MMSE). Web9 jan. 2024 · In other fields of communications, e.g., wireless communications, the maximum likelihood (ML) detector is commonly used to optimize detection performance; see [ 16, Ch, 5]. In the MC domain, the ML sequence detector has been considered for optimality in several studies. Websystem model. We consider the maximum likelihood detector that operates symbol-by-symbol (no memory) in the AWGN channel, which is later extended to frequency-ﬂat slow-fading channels with a generic SNR distribution (e.g., not limited to Rayleigh fading); no any speciﬁc assumptions about constella-tion geometry, order or dimensionality are ... lew jones portland musician

In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of an assumed probability distribution, given some observed data. This is achieved by maximizing a likelihood function so that, under the assumed statistical model, the observed data is most probable. The point in the parameter space that maximizes the likelihood function is called the maximum likelihood estimate. The logic of maximum likelihood is both intuitive and flexible, and as such th… WebIn this thesis the problem of maximum likelihood (ML) detection for the linear multiple-input multiple-output (MIMO) channel is considered.
