Optimization and performance evaluation of multicarrier transmission
IEEE Transactions on Information Theory, 1997Summary: Optimization of the performance of multicarrier transmission over a linear dispersive channel is presented. The optimum data and power assignment to the subcarriers are derived for both the conventional error probability criterion, and a new criterion based on the normalized mean-square error.

A proportional fair scheduling for multicarrier transmission systems
IEEE Communications Letters, 2005This letter extends the proportional fair (PF) scheduling proposed in the high data rate (HDR) system to multicarrier transmission systems. It is known that the PF allocation (F. P. Kelly et al. (1998)) results in the maximization of the sum of logarithmic average user rates.

Impulse noise cancellation in multicarrier transmission
2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002A parallel between Reed Solomon codes in the complex field and multicarrier transmission using OFDM is first presented. This shows that when the signal is sent over some channel composed of Gaussian plus impulse noise, the impulse noise can be removed by a procedure similar to channel decoding, using information carried by the "syndrome".

On optimizing multicarrier transmission
Proceedings of 1995 IEEE International Symposium on Information Theory, 2002Optimum conditions for maximizing the throughput of an orthogonal frequency division multiplexed (OFDM) system are derived, and an algorithm for achieving them is presented. Theoretical bounds on performance are derived and used to compare OFDM with conventional equalized single carrier QAM for both the conventional error probability criterion and a ...

Orthogonal multicarrier transmission with modal channel estimation
2009 International Conference on Telecommunications, 2009A novel multi-carrier orthogonal transmission scheme is presented. While being simpler to implement, it has a spectral efficiency and design parameters similar to those of Orthogonal Frequency Division Multiplexing based on Offset Quadrature Amplitude Modulation (OFDM/OQAM). A parametric channel estimation technique is subsequently reported.

Adaptive sub-channel equalization in multicarrier transmission
1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002In multicarrier data transmission using filter banks, adaptive equalizers can be introduced in the receiver in every sub-channel, to achieve high bit rates. Following conventional data transmission techniques, two approaches can be envisaged, namely the double sampling equalizer (DSE) and the critical sampling equalizer (CSE).
