| Abstract: | First an optimized training sequence is designed for MC-CDMA system's preamble,due to the low PAPR feature of GCL sequence.Then the proposed preamble and transform-domain processing method are combined to estimate the channel.From the simulation results,the proposed method makes a great improvement in SNR for the same BER and MSE values. |
