Abstract
A method of detecting a transmission. The method includes: measuring, from a first portion of a received spread-spectrum signal, a first code-phase of a spreading-code; measuring, from a second portion of the signal, a second code-phase of the spreading-code; comparing the first and second code-phases; and detecting whether the transmission is present according to the result of the comparison. Also disclosed are corresponding methods and apparatus for transmission and reception of signals.
