English abstract:
We propose a compressive estimator of doubly selective channels
within pulse-shaping multicarrier MIMO systems (including MIMO-OFDM
as a special case). The use of multichannel compressed sensing
exploits the joint sparsity of the MIMO channel for improved
performance. We also propose a multichannel basis optimization for
enhancing joint sparsity. Simulation results demonstrate significant
advantages over channel-by-channel compressive estimation.
