摘要： Various embodiments relate to a method of determining the presence of a spread spectrum signal, including: receiving N input samples of a signal; performing a first autocorrelation on the N input samples with a first offset; performing a second autocorrelation on the N input samples with a second offset; performing a third autocorrelation on the N input samples with a third offset; performing a fourth autocorrelation on the N input samples with a fourth offset; performing a fifth autocorrelation on the N input samples with a fifth offset; determining if the values of the first, second, and third autocorrelations are decreasing, and determining if the values of the fourth and fifth autocorrelations are less than a threshold value, then determining that a spread spectrum signal is present in the N input samples.

摘要： Disclosed is a method and apparatus for managing transmit requests among a plurality of co-located transmitting devices each associated with a wireless transmitting protocol. The method comprises the steps of determining the cost associated with each of the transmit requests, wherein the cost is associated with the cost of granting the request and the cost of rejecting the request, granting the request associated with the lowest cost, and rejecting all other requests. In another aspect of the invention, the method comprises the step of determining whether the lowest cost is acceptable and rejecting the request associated with the lowest cost when the lowest cost is unacceptable.
