摘要：The fundamental tasks that are used in the cognitive radio (CR) networks are spectrum shapingcapability and multi carrier systems. In these structures activation of fundamental (primary) users will generate adefined number of sub carriers in the second users. Therefore overall capacity of cognitive radio network is minimized.The small capacities antennas are neutralized by using OFDM based cognitive radio system although various transmitantennas are applied. These considerations examine the complication of resource allocation in MIMO based cognitiveradio networks. This paper discusses the model building of MIMO-OFDM using MATLAB R2012b version. Thismodel is a using tool for BER (Bit Error Rate), PAPR (Peak Average Peak Ratio) and transmits spectrum performanceevaluation for signal & multiple input output port by the WiMAX (IEEE 802.16) system.
