Joint blind estimation of carrier phase and frequency offset for QAM signals using circular harmonic decomposition
An algorithm is presented for joint blind estimation of carrier phase and frequency offset for signals with quadrature amplitude modulation (QAM). The algorithm is based on a circ...

Estimation of Time-Variant Channels for OFDM Systems Using Kalman and Wiener Filters
In this paper, two channel estimation schemes for OFDM systems are investigated in a time-variant channel. The orthogonality of the subcarriers is destroyed in a time-variant chann...
