Performance Improvement of an OFDM/QPSK System in Selective Fading and Frequency Offset Channel
비선택성 페이딩과 주파수 오프셋이 함께 존재하는 채널에서 OFDM/QPSK 시스템의 성능 개선
Abstract
In this paper, We have investigated the SER performance of a OFDM/QPSK system with carrier-frequency offset in a frequency non-selective fading channel. Adaptive linear equalizer is adopted to OFDH/QPSK systems for compensation of performance degradation according to the non-selective fading and carrier frequency offset. As a result of performance analysis, the more frequency offset is, the worse performance of OFDH/QPSK system is. However, when OFDH/QPSK system adopts the adaptive linear equalizer, the SER performance is enhanced to the limit range
