摘要： A method and apparatus for improving performance in communication systems is provided. In one implementation, initial encoded data that has been encoded with a rateless code is received. A quality metric is determined for a communication medium on which the initial encoded data has been received. A modulation scheme used in sending the initial encoded data on the communication medium is identified. An estimate is determined, based on the identified modulation scheme and the determined quality metric, of an amount of mutual information being received per unit of received encoded data. An amount of mutual information being received is determined, based on the determined estimate.

摘要： A method for enabling simultaneous data transmissions in a wireless network includes broadcasting a first signal from a first node, receiving the first signal by a second node, and transmitting a second signal derived from the first signal by the second node. The second signal is received by the first node. A third signal is transmitted from a third node to the first node simultaneous with transmitting the second signal. The first node receives a combination signal which includes the second signal and the third signal. The first node then decodes the third signal from the combination signal using the first signal.

摘要： A system for controlling configuration settings for mobile data communication devices and services includes a redirection server and a policy generation system. The redirection server detects a triggering event in a host system and in response to the triggering event continuously redirects data items from the host system to a wireless network. Each mobile data communication device receives data items from the wireless network and includes a device configuration stored in a memory location on the mobile data communication device. The device configuration of each mobile data communication device controls one or more functions of the mobile data communication device. The policy generation system receives a policy setting from a user interface and stores the policy setting in a user information record associated with a mobile data communication device. The redirection server detects the policy setting in the user information record and in response to detecting the policy setting transmits the policy setting over the wireless network to the mobile data communication device associated with the user information record. The mobile data communication device automatically modifies the device configuration to include the policy setting. Methods of controlling a configuration setting in mobile data communication devices are also disclosed.

摘要： Methods and apparatus for symbol timing recovery are provided. Both a coarse symbol timing recovery method and apparatus, and a fine symbol timing recovery method and apparatus are described which can be used jointly for symbol recovery, for example in phase shift keying receivers. The coarse method involves the use of differential correlations and finding the time difference in peak values of the correlation results. The fine method involves interpolation of a received digital signal, followed by filtering and timing error detection. The error detection signal is further filtered and used to control the interpolator. The methods provide for robust symbol timing synchronization.

摘要： There is provided a method for generating an error signal for an automatic frequency control (AFC) loop in a Code Division Multiple Access (CDMA) system. Sign information relating to phase differences in received pilot signals is accumulated. In one embodiment, the accumulated sign information is compared against predetermined threshold levels. The error signal is generated when at least one of the predetermined threshold levels is satisfied. In a second embodiment, the accumulated sign information is decimated. An output of the decimating step is utilized as the error signal for the AFC loop.
