Femtocell technology was suggested for solving the indoor coverage of 3G networks.With the application of this technology,the indoor signal quality can greatly improve.As the Femtocell system uses the same spectrum resources with 3G systems,it can apply cognitive radio spectrum sensing technique to solve the reuse problem of spectrum resources.The background of this paper is TD-SCDMA system.This paper analyzes the principle of spectrum sensing,shows the steps of sensing and presents the method for improving the accuracy of spectrum sensing.

Key words: TD-SCDMA;Femtocell;cognitive radio(CR);spectrum sensing
