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： A technique is provided for automatic frequency offset correction in a wireless communication system. After demodulating and decoding a received signal in a receiver, channel estimation is also performed. The technique further includes re-encoding and re-modulating the decoded and demodulated signal with a coding and modulation scheme different from the received signal. The signal is reconstructed signal on the basis of the re-encoded and re-modulated signal and estimated channel characteristics. A frequency error is estimated based on the reconstructed signal and the original received signal. A threshold for a comparator is determined on the basis of the estimated offset amount determined by the comparison threshold and the estimated frequency offset.
