Abstract:	In this paper we consider a DMT transceiver with a guard\|interval of insufficient length. We describe an algorithm that\|estimates the channel impulse response correctly independently\|of its length while keeping the guard interval at the\|preset length. The training sequence is designed such that\|inter-symbol and inter-carrier interference cancel. We then\|show that calculating the one-tap equalizer per subcarrier\|as the inverse of the channel frequency response at the subcarrier\|frequency is not optimal in presence of interference.\|We also propose an improved bitloading algorithm based on\|measured signal-to-noise-and-interference ratios.
