Abstract
A signal transmitting method, a signal receiving method, and a signal receiving device are adapted to an OFDM system. In the signal transmitting method and signal receiving method, double asymmetric training symbols are used for performing time-varying channel response estimation. In the transmitting method, asymmetric pilot sub-carriers are added in data sub-carriers to form a plurality of first and second training symbols. The pilot symbols in the first and second training symbols are asymmetrically configured. In the receiving method, a channel response corresponding to each pilot sub-carrier is estimated by using two adjacent asymmetric pilot symbols. The received data sub-carrier is then restored through the channel response. Through the signal transmitting method and signal receiving method, even in a transmitter or a receiver moving at a high speed, more bandwidths can be used to transfer data, and contents of the transferred data can be correctly estimated.
