A Hardware Demonstrator for MIMO-Communication Systems: Application to Blind Source Separation

Authors: J. Rinas, A. Scherb, T. Haase, K.-D. Kammeyer
Abstract: Our poster presents a hardware demonstrator for MIMO-communication applications. The demonstrator is capable to transmit arbitrary signals using 8 transmit and 8 receive antennas in parallel. It works in the 2.4 GHz ISM band. We illustrate the impairments of the MIMO channel with some frequency response measurements. In order to equalize the spatial channel in our MIMO-communication set-up we apply Blind Source Separation algorithms to split up the spatial channel into parallel SISO channels and to use SISO algorithms for the further processing. Some measurement results depict the feasibility of this approach. To achieve nearly the performance of MIMO detection algorithms with ideal channel knowledge it is necessary to include a decision device in a turbo fashion into our system (which makes use of the finite symbol alphabet). We display some simulation results to illustrate the performance of this approach.
