Implementation and Evaluation of 4×4 MIMO Fading Simulator Considering Antenna Characteristics

A 4 times 4 MIMO fading simulator (MIMO-FS) was constructed for the development of MIMO products. This MIMO-FS consists of multi-port up/down converters for 2.4/5.2GHz bands and baseband reconfigurable digital signal processors which allows the implementation of various MIMO channel models. In this paper, extended IEEE802.11n channel model including antenna characteristics and its hardware implementation are given as well as the system evaluation results.
