| Abstract: | The identification of the primary user is one of the most important issue in the spectrum sensing process for the cognitive radio networks. The characteristic of the primary user' signal is utilized in order to bring forward a new,practical method to recognize the real users. This paper attempts to analyze the transient signal which can be generated when the radio station starts or communication module switches by utilizing the wavelet transform and clustering. In order to identify the radio station,two ind... |
