- Abstract
Overlapping signal separation in spectrum is a difficult problem. We use Gamma Mixture Model to formulate the distribution of signal power in each frequency bin of digital phosphor technology (DPX) spectrum. Then Expectation Maximization (EM) Algorithm is used to solve the model. Simulation results show that when CIR is greater than 2.7dB, parameters’ estimation error rate of this algorithm is less than 1e-5.
