Abstract
The present invention provides a transmission method applied on Orthogonal Frequency Division Multiplexing (OFDM) system, which produces a training sequence with the same amplitude at time domain and frequency domain in sender. The sender superimposes the training sequence and data sequence then sends to receiver, so the receiver can utilize the superimposed training sequence to do semi-blind channel estimation for OFDM system. Furthermore, a weighting factor β is used to adjust the ratio of power peak value to average value.
