In the systems, orthogonal transmission beams are formed between transmit and receive sides; and also optimal transmit input data are adaptively allocated. In addition, a simple detection can be used at receiver to totally eliminate sub-stream interference. Therefore, MIMO E-SDM systems have been considered as a good potential technology for future high speed data transmission networks. Although there have been a lot of technical papers evaluated the systems based on theory analyses and/or computer-based simulation, just few ones have been considered the MIMO E-SDM systems based on hardware design. The main contribution of this paper is to present our own design and implementation of 2x2 and 2x3 MIMO E-SDM systems on FPGA Altera Stratix DSP Development KIT using Verilog HDL, an important step before going to make integrated circuits. The biterror rate performance the consumption for our design of these systems have shown that our design is successful. Keywords: MIMO, E-SDM, ZF, FPGA, hardware design. 1. INTRODUCTION Multiple-input multiple-out (MIMO) systems 802.11, 3GPP Long Term Evolution, and WiMAX have been considered as a high speed data When channel state information (CSI) is not [1–3]. transmission technology. The channel capacity of available the systems can increase significantly and is multiplexing (SDM) technique is used for data proportionally to the number of transmit (TX) and transmission. In the .
