摘要： According to an exemplary embodiment an architecture for a new integrated TDMA system capable of carrying circuit data (e.g., voice, vides, ISDN), packet data (e.g., X.25, Frame Relay, Internet, LAN), and ATM cells is disclosed. The architecture may be used for satellite and wireless TDMA networks, for example. For this transmission formats for bursts (101), channels (130, 140), TDMA frames (10) are defined and an adaptation layer for the three traffic types is described. In addition, the network has to carry its own management traffic and provide timing and control information to all terminals. For this the invention defines special bursts and along with their associated properties and formats. Each burst contains a data section which is divided into a number of channels. Each of the channels is adapted to carry protocol data units (141, 142, 143) which enable the system to efficiently allocate data according to its individual format or protocol thereby enabling maximum use of available bandwidth under prevailing communication conditions.

摘要： A method and apparatus for providing a low 2-point Cell delay variation (CDV) for cell or packet transmissions via a TDMA or TDM network, where the cells or packets are assembled in bursts or slots for transmission. In order to permit a TDMA or TDM network that carries cells or packets between source and destination pairs to guarantee that a desired 2-point CDV will be met, for example a 3 ms CDV required for Class 1 traffic, each cell is associated with a transmitted TDMA or TDM frame. Using a time counter and a frame counter in a transmitter interface, the cell or packet has appended to it a time count and a frame count that is sent across the network and made available to the receiving TDMA/TDM terminal. The receiving terminal uses this timing information to perform traffic shaping of the cell or packet stream, thereby reducing the impact of the 2-point CDV as well as the effect of cell clumping prior to distribution on a terrestrial network.

摘要： Disclosed are devices and methods related to radio-frequency (RF) shielding of RF modules. In some embodiments, tuned shielding can be achieved by utilizing different structures and/or arrangements of shielding-wirebonds to increase shielding in areas where needed, and to decrease shielding where not needed. Such tuning of shielding requirements can be obtained by measuring RF power levels at different locations of a module having a given design. Such tuned RF shielding configurations can improve the overall effectiveness of shielding, and can also be more cost effective to implement.

摘要： A method of assembling a plurality of frames including cell/packet-formatted data according to a predetermined frame format for transmission in a communication signal in a wireless or satellite environment. The method begins by assembling a data payload for each frame having a first variable size, including at least one of a partial data cell/packet and a complete data cell/packet. Then, for each frame a block code having a second variable size is generated for use in error correction. Each frame is provided with a frame header which defines aspects of said frame. Finally, the data payload, the block code and the format header are combined to form a frame corresponding to the plurality of frames, the format header defining a first portion of the frame, the data payload defining a second portion of the frame and the block code defining a third portion of the frame.
