專利摘要(英)
The present invention discloses a channel estimation method for an orthogonal frequency-division multiplexing system with cyclic-delay diversity. The method makes pilots have the same amplitude and equally partitions the pilots into a number of pilot groups. In addition, the method equally spaces the pilots of each group in a frequency domain and determines the pilot locations and cyclic-delay coefficient of each pilot group in order to optimize the channel estimation of a receiver. The method can perform the channel estimation by using just one OFDM symbol.
