Self-Orthogonalizing Adaptive Equalization in the Discrete Frequency Domain
IEEE Transactions on Communications, 1984A self-orthogonalizing discrete adaptive equalizer for synchronous data transmission is presented, based on the overlapsave filtering technique. Self-orthogonalization in the discrete frequency domain is adaptively performed by premultiplying by a diagonal matrix the MSE gradient estimates before projecting by means of Rosen's gradient projection ...

Equalization algorithms in the frequency domain for continuous phase modulations
GLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005In this paper, novel equalization algorithms for continuous phase modulations (CPMs) are illustrated. Both conventional (linear and decision-feedback) and turbo equalization techniques are derived using the Laurent decomposition of CPM signals. All of them operate in the frequency domain and process two samples of the received signal per channel symbol.

Virtual Receive Antenna System with Frequency Domain Equalization
2007 IEEE Wireless Communications and Networking Conference, 2007Vertical Bell Laboratory Layered Space-Time (V-BLAST) is one of the promising multiple input multiple output (MlMO) architectures. Layered space time processing in V-BLAST requires the number of receive antennas to be equal to or larger than the number of transmit antennas.

Blind MIMO Equalization in the Frequency Domain
2005 Australian Communications Theory Workshop, 2006Broadband wireless systems require low complexity equalizers which can cope with long channel impulse responses and severe intersymbol interference (ISI). In this paper, a frequency domain (FD) approach for adaptive blind equalization for multiple-input multiple-output (MIMO) communication systems is proposed.

Frequency-Domain MMSE Channel Estimation for Frequency-Domain Equalization of DS-CDMA Signals
IEICE Transactions on Communications, 2007Frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can replace the conventional rake combining to significantly improve the bit error rate (BER) performance in a frequency-selective fading channel. MMSE-FDE requires an accurate estimate of the channel transfer function and the signal-to-noise power ratio (SNR ...

A CMA equalization system in frequency domain
2010 IEEE 12th International Conference on Communication Technology, 2010CMA is an important equalization algorithm. CMA equalization in frequency domain is also worth studying. According to the work before, CMA was always used in the time domain but never in the frequency domain, because CMA requires that the input signal has a constant modulus feature, which is easy to achieve in the time domain but difficult in the ...
