Abstract
Techniques are presented for improving packet detection within a wireless device in the presence of platform noise. In some embodiments, packet detection is carried out by first performing a correlation operation using a signal at an input of a wireless receiver. The result of the correlation may then be compared to a threshold value in order to make a packet arrival decision. The threshold value may be varied during device operation in a manner that enhances packet detection performance.
