Yunpeng Hu · Jisuanji gongcheng · 2011
This paper addresses the problem of carrier frequency recovery in additive noise.Frequency estimation algorithm based on Support Vector Machine(SVM) is derived.The estimator can work efficiently without the need of statistics knowledge of the observations,and the estimation performance is insensitive to the carrier phase;it shows a better performance than traditional Maximum Likelihood(ML) estimation algorithm at low Signal to Noise Ratio(SNR),for SVM-FEA has not the threshold effect.
