| Abstract: | We propose a non-redundant linear precoder for MIMO-OFDM which enables blind channel estimation. Due to the structute introduced by the precoding matrix, the channel can be estimated based on general SVD. The identifiability of the proposed algorithm is guaranteed even when the channel matrices share common zeros at subcarrier frequencies. Computer experiments show that the performance of our proposed algorithm compares favorably to the training based LS algorithm. | ||
