The Overview of Dynamic Frequency Spectrum Access Based on Some Advanced Techniques

摘要：

The paper introduced the present insufficient situation of the frequency spectrum resource.Several effective techniques to raise the utilization efficiency of the spectrum and corresponding developments of their applications,such as the Cognitive Radios,the Ultra-Wide Band radio,the Water Filling Principle and the Detection & Avoidance Mechanism,are analyzed and compared,which are increasingly significant to the spectrum regulation and management research.
