Abstract(in English) | OFDM system is effective in inter symbol interference caused by multipath fading especially in the case of wide band data transmission. Nevertheless, the delayed waves existing in a symbol degrade the system performance at the receiver. Therefore when OFDM applies to mobile radio communication system, we have to remove the influence without intricacy. This paper proposes a new estimation scheme for propagation characteristics using the characteristics of OFDM signal inserted pilot signal periodically. Using this scheme, it is possible to pre-equalize the received data before FFT and to become receiving circuit smaller. And we evaluate the estimation accuracy of the proposed scheme by computer simulation. |
