摘要：Error-free transmission and increase in multimedia applications is one of the main aims of wireless communication. MIMO-OFDM is the system to improve the reliability of the WiMAX system. The fundamental tasks that are used in the cognitive radio (CR) networks are spectrum shaping capability and multicarrier systems. In these structures activation of fundamental (primary) users will generate a defined number of subcarriers in the secondary users. In this paper, the design of the MIMO-OFDM system using Matched Filter Detection Spectrum Sensing Cognitive Radio Network is presented. A matched filter is a spectrum-sensing method that detects the free portions of the primary user’s spectrum and allocates it to secondary users. It derives from cross-correlating an unknown signal with known ones to detect the unknown signal’s presence based on the basis of its SNR. Accordingly,an efficient scheme is developed here, having better SNR VSBER against a different MIMO-OFDM system.
