Abstract :
The modified forward backward linear prediction method (MFBLP) method for estimating the frequencies of multiple sinusoids performs well on short data records, but a large predictor order L is required to achieve the minimal estimation variance. A new expanded MFBLP method is presented, which attains the same (or slightly better) performance for a substantially smaller L, and a hence smaller computational complexity. For example, in the case of 2 closely spaced sinusoids and 64 samples, L opt decreases from 48 to 9, and computational complexity is reduced to less than 25%
