| Abstract: | Three different channel estimation algorithms can be used based on specially designed comb type pilots inserted in frequency domain.One of the algorithms is performed in frequency domain and the other two are performed in time domain.Numerical analyses and computational simulation show that three proposed estimation schemes have the same good performance while the time domain methods have relatively simple structure. |
