Technology for high speed data wireless transmission networks, such as IEEE 802.11, 3GPP Long Term Evolution, and
WiMAX [1-2].
The MIMO SDM technology can significantly increase channel capacity by simultaneously transmitting multiple
independent sub-streams with the same data rate and power level.
The OFDM technology can eliminate the effect of multipath fading and use given spectrum efficiently.
This paper is divided into 6 parts as follows. After a brief introduction, an overview of MIMO-OFDM SDM systems is
described in section II. In section III and IV, we present the design of MIMO-OFDM SDM system in Matlab and
hardware implementation. The results and discussion of our implementations are shown in section V. Conclusions
are presented in final part.](https://image.slidesharecdn.com/plandesignandfpgaimplementofmimoofdmsdmsystems-141129215322-conversion-gate01/85/Plan_design-and-FPGA-implement-of-MIMO-OFDM-SDM-systems-4-320.jpg)

- 6. Review and research gap Page 6 The main goals I developing next generations of wireless communication systems (still) are increasing the link throughput( bit rate) and the network capacity. The available spectrum is limited. So to fulfil above goals, future systems should be characterize by improved spectrum efficiency. Research in the information theory, performed in the early nineties, has revealed that important improvements in spectral efficiency can be achieved when multiple antennas are applied at both the transmitter and receiver side. Multiple-Input Multiple-Output (MIMO), techniques can basically be split into two groups: Space-Time Coding (STC) and Space Division Multiplexing (SDM). STC: performance. SDM: bit rate.
