| titleOfInvention | MIMO-FBMC/OQAM system channel estimation method based on compressed sensing |
| abstract | A MIMO-FBMC/OQAM system channel estimation method based on compressed sensing comprises the following steps: (a) obtaining an initial estimation value of channel frequency domain response on each pilot frequency subcarrier by using a least square method; (b) estimating the estimated value of the channel time domain response of each path of the channel by using a compressed sensing-based adaptive channel estimation method by utilizing the sparsity of the initial estimated value of the channel frequency domain response obtained in the step (a); (c) and (c) calculating the mean square error of the compressed sensing channel estimation value of each MIMO subchannel obtained in the step (b) and the original channel value to obtain the accuracy of channel estimation. The method can effectively eliminate the intersymbol interference and the subcarrier interference caused by the multipath interference, thereby improving the channel estimation precision of the MIMO-FBMC/OQAM system. |
