Abstract
Some embodiments of the invention provide devices, systems and methods of wireless signal detection. For example, an apparatus in accordance with an embodiment of the invention includes a detector to determine whether an incoming input includes a wireless communication signal intended for reception, based on an operation applied to a first auto-correlation value and a second auto-correlation value, wherein the first auto-correlation value represents a correlation between values of the incoming input at times separated by a first delay period, and wherein the second auto-correlation value represents correlation between values of the incoming input at times separated by a second, different, delay period; the first delay period is not an integer multiple of the second delay period, and the second delay period is not an integer multiple of the first delay period.
