| Abstract | Abstract—In this paper we consider a wireless link subject to on-off interference. We show that by using different size packets and by measuring the packet error rate as a function of packet transmit duration on the air, the distribution of the off times between interference bursts can be accurately estimated. In the context of white space usage, this directly corresponds to estimation of the time duration of the spectrum hole usable by a secondary station. We present simulation results demonstrating the effectiveness of the proposed technique for a range of interference patterns, and illustrate its ability to distinguish between on-off interference and channel noise and provide quantitative measures of both. By being able to carry out sensing without requiring the transmitter to remain silent, this creates the potential for significant throughput gains. I. |
