| Abstract(in English) | In this article, we propose a blind channel estimation method for time-variant channels in OFDM transmission. The proposed method combines a subspace-based estimation method and an L1 regularization technique. Using the L1 regularization, the performance degradation of the subspace-based method when the channel order is unknown at a receiver can be improved. Computer simulations show that the estimation method using L1 regularization is superior to the subspace method when the channel order is unknown. |
