MIMO-OFDM is a critical technology and a good option for 5G telecommunications networks. The present MIMO hardware and software developments, as well as MIMO-OFDM equalisation approaches, are briefly covered. Mobile devices have grown into very sophisticated communication tools that serve as sensors in a cloud computing environment. Several improvements have been made to the core network in order to provide a high quality of service (QoS) and to support novel and diverse access ways. With the introduction of the IEEE 802.22 standard, cognitive radio (CR) networks have become increasingly important in the optimal utilisation of available spectrum resources with less interference between neighbouring users. In this paper, performance analysis of MIMO-ODFM using AWGN with different modulation scheme in WiMAX technology. The results of this investigation are performing between signal to noise ratio verses BER using MatlabR2013a tool.
