Universal Decoding for Frequency-Selective Fading Channels
IEEE Transactions on Information Theory, 2005We address the problem of universal decoding in unknown frequency-selective fading channels, using an orthogonal frequency-division multiplexing (OFDM) signaling scheme. A block-fading model is adopted, where the bands' fading coefficients are unknown yet assumed constant throughout the block.

The Performance of FSK in Frequency-Selective Rayleigh Fading
IEEE Transactions on Communications, 1983This paper presents measured error-rate performance of binary FSK with discriminator detection in simulated Rayleigh fading with time delay spread. Measured relations between error rate and carrier-to-noise ratio are shown for a range of time delay spreads. We have verified that the effect of time delay spread on error rate can be described by only one

Modulation diversity for frequency-selective fading channels
IEEE Transactions on Information Theory, 2003In this article, modulation diversity (MD) for frequency-selective fading channels is proposed. The achievable performance with MD is analyzed and a simple design criterion for MD codes for Rayleigh-fading channels is deduced from an upper bound on the pairwise error probability (PEP) for single-symbol transmission.

Switched-diversity FSK in frequency-selective Rayleigh fading
33rd IEEE Vehicular Technology Conference, 1983This paper presents the measured performance of a 64 kbit/s switched-diversity FSK receiver subjected to simulated frequency-selective Rayleigh fading. The single receiver input is switched between two, three, or four uncorrelated Rayleigh-fading signals whenever the instantaneous receiver output falls below a threshold.

Optimal training for MIMO frequency-selective fading channels
Conference Record of the Thirty-Sixth Asilomar Conference on Signals, Systems and Computers, 2002., 2003High data rates give rise to frequency-selective propagation effects. Space-time multiplexing and/or coding offer attractive means of combating fading and boosting capacity of multi-antenna communications. As the number of antennas increases, channel estimation becomes challenging because the number of unknowns increases, and the power is split at the ...

Adaptive channel selection in frequency-selective fading environment
1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003This paper proposes an adaptive channel selection method that reduces signal distortion due to frequency selective fading and thereby improving the performance of mobile communication. In this method a channel is adaptively selected by estimating current channel condition with mean square decision error as a measure.

Information rates of the noncoherent frequency selective fading channel
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009This paper examines ways of improving channel estimation using successive decoding for the time varying frequency selective fading channel in a point to point wireless communication system. The channel state information (CSI) is not known a priori at either the transmitter or the receiver.

Turbo product codes on frequency selective fading channel
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003In this article, we present a new scheme that combines the turbo product codes with a simple single carrier frequency domain based equalization algorithm. By using transmit diversity in frequency selective Rayleigh fading channels, the system can resist intersymbol interference effectively.

Improved GFDM equalization in severe frequency selective fading
2017 IEEE 38th Sarnoff Symposium, 2017This paper presents a method for protecting wireless signals through the creation and exploitation of time-varying spectral redundancy. Redundant symbols are multiplexed in both time and frequency in dynamic patterns within multicarrier symbols which creates the spectral redundancy.

Cooperation over frequency-selective fading relay channels
IEEE Transactions on Wireless Communications, 2008We study information-rate calculations and coded cooperation strategies for relay channels with frequency-selective (FS) fading. We develop suitable channel trellises for the multiaccess and broadcast parts of the relay channel, and employ simulation-based techniques to calculate (approximate) ergodic information-rate bounds with FS Rayleigh fading ...
