摘要： An ATM connection (45) and call connection equipment (22) can be dynamically allocated between exchanges (20, 30). The connection is set up and released by a master switch (20) on one side of the connection. The slave (30) is controlled using standard signaling protocols and the physical connections (45) between the interworking units (40, 50) use circuit emulation according to AAL1. The master (20) controls the ATM connection (45) with standard signaling and the slave (30) with normal trunk signaling. The ATM connection (45) and connection (26) can be set up between the nodes (40, 50) when needed based on the traffic needs of the network (10).

摘要： Television receivers receive a television signal and downconvert the television signal to generate a complex baseband signal. The complex baseband signal is differentiated and then integrated to reduce a direct current (DC) offset in the complex baseband signal. The television receiver may include a periodic known information field. The known information field is correlated with the integrated signal to determine a residual offset therein that is associated with a constant used in integrating the differentiated complex baseband signal. The residual offset is subtracted from this constant when integrating the differentiated complex baseband signal.

摘要： A device and method is provided that transmits a monitor report to the current base station concurrently with the transmission of the informational content carrying signals by embedding the monitor report in the informational content carrying signals. The current base station uses the monitor report to initiate transfer of service for the mobile communication device to the base station with the strongest carrier signal strength by sending appropriate signals to the mobile switching center that in turn signals the base station to take over service for the mobile communication device. A wideband digitizing circuit obtains amplified wideband analog signals from the receiver before channel filtering and demodulation, and converts them to complex digital samples. The digital samples are obtained at a rate greater than the Nyquist rate for the total scanned bandwidth but are only taken during a very short time interval commensurate with the reciprocal of the channel spacing, thereby reducing power consumption to a minimum. The digital samples are then operated on by a microprocessor or signal processor to determine energy in a plurality of channels, preferably using a fast Fourier transform. The analysis results in an indication of the channels containing the strongest signals and this information is provided in the monitor report sent to the current base station.

摘要： A transmit diversity scheme for a CDMA system uses space-time codes to obtain diversity gain. Combined diversity signals encoded according to a space-time code are received at the mobile terminal during first and second symbol periods. The mobile terminal includes a first Rake receiver matched to a first transmit antenna and a second Rake receiver matched to a second transmit antenna. The first Rake receiver combines multipath echoes of the first combined signal during the first symbol period to obtain a first value and combines the multipath echoes corresponding to the second combined signal during the second symbol period to obtain a second value. The second Rake receiver combines multipath echoes corresponding to the first combined signal to obtain a third value and combines multipath echoes corresponding to the second combined signal to obtain a fourth value. A decoder decodes the first, second, third, and fourth values to obtain final estimates of the transmitted symbols.

摘要： A cellular mobile telecommunication system includes a mobile station communicating with any one of a plurality of geographically spaced base stations, the base stations communicating with a mobile switching center to selectively determine one of the base stations to process a call with the mobile station. A handoff system hands off a cellular call with the mobile station from one base station to another base station. The handoff system includes a forward communication channel selectively associated with the one base station for transferring data from the one base station to the mobile station. The one base station is adapted to receive a command from the mobile switching center to handoff processing of the call to another base station, the command including information on capabilities of another base station. A message generator operatively associated with the one base station sends a capability change indicator to the mobile station via the forward communication channel and responds to a handoff command from the mobile switching center. The capability change indicator includes information on capabilities of the another base station relative to the one base station.

摘要： A joint demodulator is configured to generate an estimated first frequency or first frequency error for the first signal and an estimated second frequency or second frequency error for the second signal. A first long-term automatic frequency control is responsive to the estimated first frequency or first frequency error, wherein the joint demodulator is responsive to the first long-term automatic frequency control. A second long-term automatic frequency control is responsive to the estimated second frequency or second frequency error, wherein the joint demodulator is responsive to the second long-term automatic frequency control. First and second local automatic frequency controls also may be included in the joint demodulator, wherein the first long-term automatic frequency control is responsive to the first local automatic frequency control and the second-long-term automatic frequency control is responsive to the second local automatic frequency control. The first long-term automatic frequency control and the second long-term automatic frequency control can produce respective first and second frequency offset signals that are applied to the joint demodulator. Alternatively, a difference between the first and second frequency offsets is applied to the joint demodulator and the first frequency offset is applied to a downconverter that downconverts the jointly received first and second signals and provides the downconverted signals to the joint demodulator.
