A wireless communication system can be tested either in actual conditions or by using a hardware simulator reproducing actual conditions. With a hardware simulator it is possible to freely simulate a desired type of a radio channel. This paper presents new frequency domain and time domain architectures for the digital block of a hardware simulator of Multiple-Input Multiple-Output (MIMO) propagation channels. This simulator can be used for Wireless Local Area Networks (WLAN) 802.11ac applications. It characterizes an indoor scenario using TGn channel models. After the description of the general characteristics of the hardware simulator, the new architectures of the digital block are presented and designed on a Xilinx Virtex-IV Field Programmable Gate Array (FPGA). Their accuracy, occupation on the FPGA and latency are analyzed.
