摘要：
OFDM is used in many applications that require high-speed communication. However, in OFDM under impulsive noise, the reception characteristics are strongly deteriorated by impulsive noise because impulsive noise has short time duration and very large magnitude. Therefore, it is necessary to reduce the influence of impulsive noise. In the compensation of impulsive noise, the channel condition is estimated by using pilot symbols. In this paper, the reception characteristics are improved under impulsive noise by the proposed scheme using scattered pilot symbols.
