Orthogonal frequency division multiplexing (OFDM) is used for broadband communications over power line due to its ability to adapt to complex transmission channel structures. OFDM is a multicarrier modulation system based on the discrete Fourier transform. However, its poor spectral containment decreases the system performance in front of narrow-band interferences. In order to improve the performance of the communication system, general MCM systems are implemented using filter bank transformations. Both perfect reconstruction and near perfect reconstruction filter banks are considered. It is shown that near perfect reconstruction filter banks achieve the lowest probability of error. Lately, in order to implement these techniques to frequency selective channels, a set of equalization techniques are presented and their performances are evaluated.
