摘要： A method for detecting the presence of a television signal embedded in a received signal including the television signal and noise is disclosed. Either first-order or second order cyclostationary property of the signals may be used for their detection. When the first-order cyclostationary property is used, the following method is used, the method comprising the steps of upsampling the received signal by a factor of N, performing a synchronous averaging of a set of M segments of the upsampled received signal, performing an autocorrelation of the signal; and detecting the presence of peaks in the output of the autocorrelation function. When the second order cyclostationary property of the signal is used, the method comprising the steps of delaying the received signal by a fixed delay (symbol time), multiplying the received signal with the delayed version, looking for a tone (single frequency) in the output.

摘要： The present invention provides a method and system for implementing asynchronous portal pages, comprising a portlet monitor resident on a web browser and implemented with a script. When a user interacts with a portlet, the portlet monitor sends a XMLHTTP request to the portal server. The portal server obtains the corresponding web contents from the corresponding portlet based on the request. Then, the web contents are modified and the HTTP requests therein are redirected to XMLHTTP requests. The portlet monitor uses the modified web contents to refresh the web contents of the corresponding portlet in the portal page without reloading the whole portal page. Besides, after the user submits a request for a portlet, during waiting for the portlet being refreshed, the user may continue to interact with other portlets. Thus, the present invention has the abilities of partially refreshing and asynchronous communication.
