This paper proposes a new self-recovery (blind) receiver scheme for spatial multiplexing over finite-impulse-response (FIR) fading channels. This scheme exploits the structure of second-order statistics and the non-Gaussianity of the signals. Operating without assuming prior knowledge on the channel impulse responses, the receiver even is able to operate when subchannel orders are difficult to be estimated accurately. Additionally, the new receiver scheme employs a group of FIR equalizers to gain the advantage of the frequency-selectivity, ie. multipath diversity. Simulations verified that the proposed technique is effective in suppressing the inter-symbol interference (ISI) residuals and noise components so that it substantially improves the overall system performance. This scheme is aimed at achieving a favorite trade-off between the complexity and the system performance.
