<p>A method for providing communication over a white space channel without causing interference are disclosed. The method generates a first request to identify at least one available white space channel (215), and applies a spreading sequence to the first request to generate a second request (320). The method applies a modulation to the second request to generate a third request in the time domain (350), and transmits the third request via a wireless communication to at least one other user (340). Alternatively, the method receives a request wirelessly, wherein the request comprises a request for availability of at least one white space channel, and applies a demodulation on the request to generate a demodulated request. The method applies a spreading sequence on the demodulated request to generate a de-spread request, and processes the de-spread request by determining availability of at least one white space channel.</p> |
