摘要： An original data stream is encoded into a high priority data stream and a low priority data stream. The high priority data stream is encoded so as to permit decoding of the high priority data steam independently of the low priority data stream. The high priority data stream is transmitted twice, while the low priority is transmitted in two portions, but only once. If both the first portion and the second portion of the low priority data stream are received, and at least one complete transmission of the high priority data stream is received, then the two data streams are combined to "produce a signal output of high quality. However, if any portions of the low priority data stream is lost' then the low priority data stream is not used, and only the high priority data stream is used to produce output. Overall throughput is greater than would be achieved if the original data stream were transmitted with complete redundancy.

摘要： A satellite communication system designed to communicate with wireless communication devices (WCDs) by use of a mosaic pattern of signal beams uses multiple beams to augment the communication with individual WCDs. In addition to communication with a WCD through a primary beam for that WCD, adjacent beams are used, but with signals utilizing circuit parameters assigned to the primary beam. The signals from a given WCD are relayed in a backhaul, either as an aggregate signal processed by the satellite, or as backhaul communication signals to be combined or separated on the ground.

摘要： System and method for optimally updating a neighbor set for use by a mobile unit during soft handoff of the mobile unit in a CDMA cellular telephone environment is disclosed. A two-step process is used to ensure that the individual neighbor sets of active set members are combined in a manner such that only pilots representing the more important sectors are included in the updated neighbor set and pilots representing the less important sectors are excluded therefrom. In the first step, active set members whose RTD is more than twice as great as an OWD threshold are eliminated from consideration. In the second step, the neighbor set of the mobile unit is updated using the sectors included in the individual neighbor sets of the active set members that were not excluded by the first step, wherein those sectors are included in the updated neighbor set according to the number of individual sets in which they are found and their priority within those sets. In an alternative embodiment, a combined carrier-to-interference ratio for each of the individual neighbor set members is also used in updating the neighbor set. In an alternative embodiment, the individual neighbor set of the active set member having the shortest RTD is used as the updated neighbor set.

摘要： A communication system is provided that allows a mobile terminal with an EVDO interface to perform VoIP communications via a satellite. The 1xEVDO physical layer frames and vocoder frames are synchronized and aligned to a known periodic time boundary for efficient transmission. A reverse link transmission rate is adjusted to match a VoIP packet source rate and operate the reverse link transmission channel to a satellite continuously. The reverse link transmission channel from a mobile terminal to a satellite may operate continuously and at a lower channel transmission rate to reduce the peak power amplifier power requirement. The higher layer time-out periods are increased to account for propagation delay to/from a satellite relay. A physical layer retransmit mechanism is disabled to ignore ACKs/ NACKs when sending VoIP packets via a satellite relay. A different channel code may be selective applied depending on the size/type of packets being transmitted.
