Abstract
AbstractAn orthogonal frequency division multiplexing (OFDM) transmission system is known to exhibit superior performance compared to a single carrier system in a multipath environment. However, the communication quality degrades severely because of delayed waves exceeding the guard interval and the Doppler shift. To solve this problem, various systems have been proposed that use an adaptive array to suppress undesired signals. In this paper, we propose a system that uses the same signal in the guard interval inserted at the head and the guard interval at the tail of the OFDM effective symbol in an OFDM transmission system and operates a minimum mean square error (MMSE) adaptive array. To clearly show the effectiveness of the proposed system, we analyzed the basic performance by a computer simulation. These results demonstrated excellent operation as an MMSE adaptive array and superior undesired signal suppression. © 2003 Wiley Periodicals, Inc.
