摘要： In a method and apparatus for processing ECG signals for the purpose of detecting low-amplitude signal structures hidden in noise in the ECG signal, the ECG signals, number of cardiac cycles are analog-to-digital converted, and QRS complexes in the converted signals are detected. The signals from at least two cardiac cycles are cross-correlated, and the correlation between these signals in time intervals which comprise at least the time intervals of the two samples is determined. An output quantity representing the degree of correlation is thus obtained, the magnitude of this quantity designating the amplitude of the signal structure in question. This magnitude can then be analyzed to determine if, and where in the signal, the signal structure arises.

摘要： A system and method for delivery confirmation of a short message comprising sending the short message to an recipient communication device, determining that an instant message delivery notification (IMDN) is not received, and indicating delivery failure of the short message to the mobile station. In another aspect, if a 202 Accepted message is received, the IM server is subscribed to. Alternatively when a message indicating that an recipient communication device is reachable is received, the service center sends the short message to the communication device. In another alternative, if a recipient absence notification is received the short message is buffered in a service center until the service center receives notification that the recipient communication device is present. Upon receipt of the notification, the service center retransmits the short message, and a successful delivery report is sent when the short message is received by the recipient communication device.

摘要： A method and apparatus for interworking between push-to-talk over cellular (PoC) systems and instant messaging (IM) systems is provided. An interworking entity that behaves like a PoC client to a PoC server and as an IM client to the IM server is provided. The interworking entity may be implemented as part of the PoC server or the IM server. The interworking entity listens to talk bursts from the PoC server and when it receives a talk burst the interworking entity sends the message to the IM client via the IM server. In an embodiment, the interworking entity listens to talk bursts or audio clips from the IM server and when it receives them, stores them in a temporary storage memory and converts them to a streaming format. The interworking entity then requests the floor from the PoC server, and, once the floor is granted, streams the stored audio clip or talk burst to the PoC server. The PoC server then distributes the clips to the PoC clients.

摘要： A method and apparatus for implicit floor control in push-to-talk over cellular system. A message is generated by a client in a communication system and is then streamed to a push-to-talk server. The server checks to see if the floor is idle, and if so, distributes the message to at least one other participant in the communication session. If the floor is not idle, the new message is stored and queued for distribution after all other messages ahead of the last received message have been distributed.

摘要： A receiver can identify the source of a signal from an unsynchronized source. The receiver has an antenna for receiving two signals. The receiver correlates the first signal with a code to find a first location in time, and correlates the second signal with the same code to find a second location in time. The receiver calculates a time difference between the first location in time and the second location in time and uses the time difference to identify the source of the two signals. A group of base stations or directional antennas use the same long code and synchronization codes. However, each source shifts the long code by a different amount so that for any two sources there is a unique difference between the shifts in the long code. Each source shifts a set of synchronization codes the same amount as the long code. The synchronization codes can be any short code that is relatively easy for the mobile station to detect. When the receiver receives the two signals, the receiver calculates the difference in the shifts. Because there is a unique difference for each pair of sources, the receiver can identify the source of a signal from an unsynchronized source without having to connect to the source to use a broadcast channel or control channel. The receiver can distinguish between different synchronized sources without any prior synchronization.

摘要： The present invention provides a system and method for reducing the power consumed by a RAKE receiver. In exemplary embodiments of the present invention, an environment variation estimator is implemented in a CDMA mobile station. The environment variation estimator is connected to the searcher of the RAKE receiver and provides an estimate of the rate at which the mobile station's environment is changing. By providing an estimate of the rate of change of the mobile station's environment, the duty cycle of the searcher can be optimized, thereby reducing the overall power consumed by the receiver. By also providing the estimate to the RAKE fingers, channel tracking can be improved.

摘要： In a communication system including at least one transmitter and at least one receiver, a frequency offset between a carrier frequency of the transmitter and a local frequency reference of the receiver is estimated. A phase difference is computed between successively collected samples of a frequency synchronization signal transmitted by the transmitter and detected by the receiver. The phase difference is added to accumulated phase differences. Phase differences of successively collected samples are computed and added to accumulated phase differences until M accumulated phase differences have been added. The sum of the M phase differences is dumped, resulting in zero accumulated phase differences. Phase differences of successively collected samples are computed, the phase differences are added to accumulated phase differences, and the sum of M phase differences is dumped until N sums of M phase differences have been dumped. The N sums of the M phase differences are added to produce the estimated frequency offset.

摘要： Code division multiple access signals received through at least one multipath propagation channel are processed to produce at least one relative frequency error estimate. This involves receiving and processing the signals using a local frequency reference oscillator to obtain representative complex numerical samples for processing. The complex numerical samples are correlated with shifts of a locally generated despreading code and a number of complex channel estimates are produced, each corresponding to a different delayed ray of the at least one multipath propagation channel. A frequency error estimate is computed for each ray based on successive values of a respective one of the channel estimates, and a weighted summation of the frequency error estimates is performed to provide at least one relative frequency error estimate.
