摘要： In a method of discriminating a received spread spectrum signal among a number of received spread spectrum signals that are transmitted over a transmission channel, the received spread spectrum signal is despread, thereby using a locally generated pseudo noise sequence with a given phase offset. The despread received spread spectrum signal is quantized so as to obtain a probability mass function estimate of the despread received spread spectrum signal. A difference is determined between the probability mass function estimate and a true probability mass function that corresponds to a transmitted spread spectrum signal before transmission over the transmission channel. The difference is accumulated over a given number of symbols so as to obtain a statistic of the received spread spectrum signal. If the statistic fails a test against a given threshold, the received spread spectrum signal is rejected. Otherwise, the statistic is accepted.

摘要： Reliable decoding of quick paging channel is provided using first and second page indicators carried in a quick paging channel of a wireless communication system. First and second threshold values are established to determine whether the first and the second page indicators each, as received from a base station to a mobile station, is highly reliable, reasonably reliable, or unreliable. Preferably, the pilot strengths for the first and the second page indicators each is compared with the first and the second page indicators. Depending on the level of reliability of the first and the second page indicators, different actions are taken to determine whether the mobile station enters a sleep mode or decodes a next paging channel slot.

摘要： A frame error rate of received frames is estimated. Received frames are error correction decoded. It is determined whether an error correction decoded frame is a good frame. A decoded good frame is error correction encoded. The frame error rate is estimated on the basis of the error corrected good frame and a received frame.

摘要： A remote access device is configured to communicate with each Bluetooth device within a locale. When communication is desired between two Bluetooth devices within this locale, the remote access device allows the user to send commands and other information from the remote access device to each Bluetooth device to effect the initialization of the communication channel between the two devices. Using the remote access device, the user can make selections on each Bluetooth device, enter PINs as required, respond to confirmation requests, and the like. Because each Bluetooth device may be distant from the remote access device and distant from each other, the use of the remote access device allows a user to enable communications between the Bluetooth devices without traveling back and forth between physically separated Bluetooth devices.

摘要： A system and method is provided that searches for the frequency and phase of a CDMA transmission in an iterative manner. With its automatic frequency control (AFC) disabled, the receiving system performs a coarse search for the transmitter's CDMA phase at a nominal receiving frequency. When the coarse phase is obtained, the AFC is invoked with a large-range pull-in, to obtain an initial, coarse frequency that is likely to be closer to the transmitter's frequency than the initial nominal frequency. At this coarse frequency, the receiving system repeats its search for the transmitter's CDMA phase, starting at the previously determined coarse phase. Because this second phase determination is conducted in the presence of less frequency error, it provides for a more accurate phase determination. The AFC is again invoked, but with a small-range pull-in, to obtain a finer frequency determination. Because the finer frequency determination is conducted in the presence of less phase error, a substantial improvement in the accuracy and precision of the frequency determination can be achieved. To achieve this more accurate phase and frequency determination within the same time duration as a conventional acquisition process, the initial coarse phase determination is conducted using a rapid, albeit less accurate, process than the conventional phase determination.
