摘要： A method of detecting a silent frame at a mobile station in a GSM transmission is disclosed. The method comprises first receiving a data burst intended for the mobile station. Then, a signal-to-interference-and-noise ratio (SINR) is determined for the data burst. If the SINR is below a predetermined threshold, then the data burst is determined as from a silent frame.

摘要： The embodiments of the present invention relate to the general area of wireless communication systems and, in particular, to channel estimation for joint detection of data signals in TD-SCDMA systems. While time slots and spreading codes separate the users in a TD-SCDMA system, multiple access interference affects all its users. To deal with this problem detection schemes such as joint detection are used, which process all users' signals in parallel and include the interference information from all the users. An important part of the joint detection process is channel estimation and, as such, affects the detection process in different ways. In general, the more accurate the channel estimation is, the better the system performance will be. This invention presents methods and systems for channel estimation of TD-SCDMA systems.

摘要： The present invention provides systems and methods for faster acquisition and more stable tracking of spread spectrum signals with lower computational load requirements. Instead of the present day practice of using only the Prompt correlator, the systems and methods of the invention use the sum of the powers of all the correlators of a channel to determine the acquisition or tracking of the signal. These systems and methods improve the signal acquisition speed resulting in a reduced Time-To-First-Fix (TTFF). Further, these systems and methods improve the acquisition and tracking sensitivity of the receiver.
