Abstract

In this proposal, we propose a subsymbol equalization technique for Multicarrier systems. We try to recover a small portion of the long time domain symbol, a subsymbol, by the frequency domain one-tap equalization. We introduce two applications of the subsymbol equalization. The subsymbol equalization technique is used for bandwidth efficient transmission in an OFDM system. We also propose a new non-synchronized sampling scheme (fixed free-running oscillator is used for the sampling time generation) in the DMT receiver as the second application of the subsymbol equalization.
