C34. Enhanced blind, adaptive channel shortening for multi-carrier systems

Abstract

This paper proposes a new blind, adaptive channel shortening for multi-carrier systems. We use the DST; along with its inverse as a replacement for the inverse fast Fourier transform/fast Fourier transform (IFFT/FFT) stages in DMT systems. The performance of the discrete Fourier transform-DMT (DFT-DMT) system is investigated with the proposed DST-DMT system over the standard carrier serving area (CSA) loop1, the results in this paper show that employing the proposed DST-DMT system rather than the conventional DFT-DMT system can provide a higher bit rate.
