Abstract :
A simple time domain matrix description of the intersymbol and interchannel interference (ISI/ICI) existing in multicarrier modulation schemes with guard interval is presented; it is exploited for the design of two fast algorithms for computation of the ISI/ICI power spectral density. The discussion is carried out for an ADSL modem with a general guard interval, including cyclic prefix and trailing zeros as special cases. The proposed algorithms can be utilized for estimation of the modem bitrate, for example during optimization of the time equalization (TEQ) filter.
