Abstract
In this paper, a spectrum sensing module of cognitive radio for a high speed WLAN is proposed, which aims at a G-bit data transmission rate. Energy detection for spectrum sensing is selected due to its needless of knowledge of PU signal. Also, a new method of adaptive threshold generation mechanism is introduced and accomplished. Both simulation and implementation are done and the performance is analyzed. With all the above work completed, this potential application may be used for the future WLAN to achieve higher performance. In addition, the aspects of potential methods to improve the performance of this module are provided for further study.
