Wireless OFDM-based modem using TX time-domain equalizer and data transmission method thereof

摘要

The wireless OFDM modems and data transmission method of a data packet communication system is disclosed that can be applied to the TEQ. The present invention calculates the coefficient of the transmitter TEQ using the data received at the receiver , the time domain equalization is applied to the data to be transmitted using the TEQ filter in the transmitter to adapt the calculated coefficient . The present invention can improve the transmission performance by reducing the length of the channel response of the change applied to many wireless data transmission of the TEQ was used on the wired channel wireless OFDM -based modem .
