Performance of fractionally spaced blind channel shortening

Résumé

In this paper we derive the Multicarrier Equalization by Restoration of RedundancyY (MERRY) algorithm for a fractionally-spaced channel shortening (or time domain equalizer) (FSTEQ and show that the FSTEQ MERRY algorithm converges significantly faster than the non-fractional TEQ MERRY algorithm. The main reason is that a fractionally-spaced blind adaptive TEQ admits infinitely many realizations of perfect channel shortening for a specific delay whereas a non-fractionally-spaced TEQ admits only one realization. Computer simulation demonstrates the performance improvement provided by the blind adaptive fractionally-spaced TEQ using MERRY algorithm for multicarrier systems.
