| Abstract: | Universal Filtered Multi-Carrier(UFMC)technology is a new novel of multi-carrier technology and one of the fifth generation communication system(5G)alternative waveform technologies.The system is introduced,and then for the channel estimation problem of the system,a least square(LS)channel estimation algorithm based on wavelet threshold denoising is proposed.First using the LS algorithm to obtain the channel response at the pilot frequency,then use the interpolation algorithm to obtain the full response of the channel,and finally use wavelet denoising to eliminate noise interference in the channel.Experimental simulations show that compared with the LS algorithm,the proposed channel estimation algorithm has lower bit error rate and more accurate channel estimation. |
