Title:
METHOD AND APPARATUS FOR ESTIMATING TRANSMISSION LINE CHARACTERISTICS IN OFDM COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2005151377
Kind Code:
A
Abstract:
To provide a method and apparatus for estimating transmission line characteristics in an OFDM communication system in which noise components can be remarkably eliminated.
The apparatus for estimating the transmission line characteristics in the OFDM communication system comprises: a DCT circuit 7 that receives a preamble signal; a noise elimination circuit 8 that receives a signal from the DCT circuit 7; and an IDCT circuit 9 that receives a signal from the noise elimination circuit 8 and transmits the signal to a frequency base equivalent circuit 10.
