| Summary: | 碩士 === 國立交通大學 === 電機與控制工程系所 === 92 === We propose a blind channel estimation method for OFDM systems based on finite alphabet property. The method called ratio is to make use of the property of slow phase change between two adjacent tones to cancel phase ambiguity. The proposed method needs less computation load compared with other existing methods. According to simulations, the proposed method has performances close to other existing ones on both channel estimation error and bit error rate.
