Abstract
A despreading method is applicable to a touch sensitive screen including multiple first electrodes being parallel to a first axis and multiple second electrodes being parallel to a second axis. The despreading method includes the following steps: coupling at least two of the second electrodes as a synchronization channel; despreading a first preamble code of a first signal frame of received signal from the synchronization channel to retrieve a first synchronization information according to a first pseudo noise code; and decoding a first data code behind the first preamble code of received signal from at least one of the first electrodes in accordance with the first synchronization information and the first pseudo noise code.
