Global frequency estimation using adaptive identifiers
نویسنده
چکیده
Online estimation of the frequencies of a signal which is the sum of sinusoidals with unknown amplitudes, frequencies and phases is made through yet another well-known and simple system theoretical tool—adaptive identifiers. Convergence of the proposed estimator is proved. The new frequency estimator is of 3 order, as compared to the order 5 1 resulting from Marino–Tomei observers. Results are demonstrated via simulation.

Empirical Mode Decomposition based Adaptive Filtering for Orthogonal Frequency Division Multiplexing Channel Estimation
This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system. In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...

Abstarct In this paper, combination of channel, receiver frequency-dependent IQ imbalance and carrier frequency offset estimation under short cyclic prefix (CP) length are considered in OFDM system. An adaptive algorithm based on the set-membership filtering (SMF) algorithm is used to compensate for these impairments. In short CP length, per-tone equalization (PTEQ) structure is used to avoid i...
