摘要： A method for reducing a signal-to-noise ratio requirement in a time division multiple access (TDMA) link of a mobile network. The network includes a first node and a second node. The method includes receiving at the first node, an initial TDMA signal burst transmitted from the second node, and determining link state variables, thereby synchronizing the first node to the TDMA signal burst. The method further includes tracking the link state variables between the initial TDMA signal burst and subsequent receptions of TDMA signal bursts from the second node at the first node.

摘要： According to the present invention, all terminals can establish synchronization in a radio communications system formed only of a plurality of mobile terminals. This radio terminal communicates by the time division connection method, and comprises a control portion for synchronizing its transmission/reception timing to that of a group including a plurality of radio terminals. The control portion determines the overall cycle including basic cycles in a number corresponding to the number of radio terminals within said group, conducts control to transmit a signal in a basic cycle that is included in said overall cycle and that is set by a unique terminal number allotted in advance to each of said radio terminals, conducts control to receive signals from another radio terminal in another basic cycle, adjusts the transmission/reception timing based on the data received from said other radio terminal in said other basic cycle, and saves the reception timing until a process to adjust the transmission/reception timing is conducted.

摘要： In a communication system for carrying out satellite communication through a satellite among users, a satellite communication center is located in a terrestrial network, such as an internet, and has a program table accessible through the terrestrial network and representative of a time schedule of each program to be broadcast through the satellite. The program table can be reserved to broadcast contents by a sender through the internet when an empty time zone is left on the program table. When the reservation is accepted, the contents are sent from the sender through the internet to the satellite communication center and are broadcast at a reserved time through the satellite to other users in accordance with the program table. The contents may be stored in advance in an information storage of the satellite communication center once before they are broadcast or be directly broadcast to the satellite at the reserved time.

摘要： Methods and apparatus for canceling co-channel interference in a receiving system using spatio-temporal whitening. In some embodiments, a spatio-temporal interference canceling method, and apparatus for carrying out the method are provided which effectively cancel co-channel interference despite frequency offset between the desired signal and the interferer in a TDMA type system. Real and imaginary component values of the total received signal are used for virtual diversity branches, and a vector-valued auto regressive model is used to characterize the interference. In other embodiments, spatio-temporal interference whitening is used to improve timing estimates used for synchronization. The two uses of spatio-temporal whitening can be combined in one receiver. The invention is typically implemented in one or more programmed digital signal processors or application specific integrated circuits (ASICS), embodied in a receiving system.

摘要： A wireless local area network (20) includes a hub access point node (22), any number of active nodes (24) and any number of inactive nodes (26). Some of the active nodes (24) act as forwarding nodes (32) so that the coverage area of the network (20) is extended beyond the radio range of the hub access point node (22). Time slots (42) are consecutively scheduled for the active nodes (24) along outward communication paths (34) and inward communication paths (36). Beginning time slots (42) for the inward communication paths (36) are assigned to outermost nodes (38) in the paths (36). Beginning time slots (42) for the outward communication paths (34) are assigned to the hub access point node (22). Time slots (42) are assigned in a manner that minimizes total latency (44). Time slots (42) are also assign to afford opportunities for the inactive nodes (26) to communicate.

摘要： Location-based call management methods for geographically-distributed communication systems, including conventional (FIG. 1) and trunking (FIG. 3) systems operable in full duplex mode. A base station controller (111) of a conventional system receives (202) a message, determines (204) a message priority and sends (210, 214, 220) the message to recipient devices selected from among a console (122), local base station (101) and adjacent base station(s) (102, 103) based on the message priority. A zone controller (308) of a trunking system determines an associated site (301) and one or more adjacent sites (302, 303) for a prospective talkgroup call and, based on availability (406, 416, 428) of resources, assigns (424, 432) site(s) to the call. A mobile communication device (320) determines (506, 510) a selected site and adjacent site(s) and respective talkgroups, affiliates (508) with the selected site talkgroup and enters (512) the adjacent site talkgroup(s) in a scan list. Thereafter, the communication device is able to receive (518) calls for the affiliated or adjacent site talkgroups.

摘要： A TDMA radio terminal comprises a transmitter portion and a receiver portion. A reference signal is launched in the transmitter portion while tuning the receiver portion. At the same time, an internal delay counter is started. The counter counts clock pulses till the reference signal returns through the receiver portion. Letting this pulse count be Nd, a transmission wait time is NtnullNd. Nt is a transmit timing at the antenna. The Nd counting operation may be triggered by a power on or a signal from a controller. Method for determining the transmission wait time in the production site is also disclosed.

摘要： A method of and system for determining an ability of a first device to use an optical trail to communicate across an optical transport network with one or more other devices. The first device and the one or more other devices are external to the optical transport network. A first signal is transmitted from the first device, where the first signal indicates that at least a first port of the first device is available to be an endpoint for an optical trail across the optical transport network. The first signal is received at a first transport network device of the optical transport network. A second signal is transmitted from the first transport network device, where the second signal identifies a second port of a second transport network device included in the optical transport network to which the first device can send signals corresponding to an optical trail. The second signal is received at the first device.
