Blind MIMO Channel Estimation Based on Structured Transmit Delay

This paper aims to relax the restrictive conditions on blind MIMO channel identification by exploiting structured transmitter design. First, a simple structured transmit delay scheme is proposed, in which each antenna transmits an independent zero-padded data stream. Secondly, a second-order statistics based blind channel estimation algorithm is developed. Simulation results demonstrate that the proposed approach is robust in MIMO environment, even if when there are common zeros among the sub-channels
