This paper proposes a high capacity MIMO (multi input multi output) architecture based on blind deconvolution (BD). BD is a technique for blindly deconvoluting convolved independent signals. By dividing one user's data stream into multiple data streams, we can realize a MIMO system which has M-time higher capacity than a SISO system. In this paper, we propose a method which can apply PSK and QAM modulated signals to BD. From the simulation results, we have verified that this method effectively recovers PSK or QAM modulated signals that are mixed and convolved in a multipath channel.
