Maximum-likelihood scintillation detection for EM-CCD based gamma cameras.

Gamma cameras based on charge-coupled devices (CCDs) coupled to continuous scintillation crystals can combine a good detection efficiency with high spatial resolutions with the aid of advanced scintillation detection algorithms. A previously developed analytical multi-scale algorithm (MSA) models the depth-dependent light distribution but does not take statistics into account. Here we present a...

Maximum Likelihood Frequency Detectors for Orthogonal Multicarrier Systems

In this paper we derive a frequency estimation algorithm for a multicarrier system based o n the mazimum likelihood principle. We propose a frequency detector structure directly based on this algorithm and a reduced complezity structure having the same performance. However, such a detector shows a very small acquisition range due to the particular f o r m of the likelihood function f o r a mult...

Distance Enhancing Constraints for Noise Predictive Maximum Likelihood Detectors

|Using performance analysis of Reduced State Sequence Estimators (RSSE), we characterize dominant error events for a Noise Predictive Maximum Likelihood (NPML) detector. The error event characterization may be used to determine distance enhancing constraints that improve the reliability of NPML/RSSE detection. An example of a constraint that provides approximately :8 dB asymptotic coding gain f...
