الكلمات الدالة This article presents a new time domain equaliser (TEQ), which can be used in
discrete multi-tone (DMT) systems to maximise the bit rate. The proposed TEQ is
tested in the fast Fourier transform based discrete multi-tone (FFT–DMT)
system, and in a proposed discrete cosine transform based discrete multi-tone
(DCT–DMT) system. The objective of the proposed DCT–DMT system is to
make use of the energy compaction property of the DCT to reduce the channel
effects on the transmitted signals. A mathematical model of the proposed TEQ is
presented. Simulation experiments have been carried out to test the effect of the
proposed TEQ with the FFT–DMT system and the proposed DCT–DMT system.
The results show that the performance of the DCT–DMT system with the
proposed TEQ is better than the FFT–DMT system with this TEQ over the eight
standard carrier serving area (CSA). The results also show that employing the
proposed TEQ in the DCT–DMT system can achieve a high bit rate, ranging
from 2.899 Mbps to 5.369 Mbps.
