Optimisation and performance evaluation of OFDM transmission / T.J. Willink, P.J. Vigneron and P.H. Wittke.: Co24-3/8-1998-1E-PDF
"In this technical note, the optimisation of OFDM transmission over a linear dispersive channel is considered. The optimum data and power assignments to the subcarriers are derived for both the conventional error probability criterion, and a new criterion based on the normalised mean-square error. The assignments and algorithm hold for channels where performance is degraded by additive noise, intersymbol and interchannel interference. Lower bounds on throughput are derived and are used to compare OFDIVI performance with conventional single carrier QAM with both linear and decision feedback equalisation. It is shown that OFDM transmission can provide a significant improvement at low and intermediate channel SNRs. The case of a multiuser multicarrier system is considered, in which interference from adjacent users affects the OFDM allocations. A sub-optimal, but more practical, approach to maximising OFDM performance is presented"--Abstract, page iii.
