    摘要: A wireless access unit (12) for providing an interface between a satellite communications system (32) and a plurality of terrestrial user devices (14-26) in a centralized or distributed architecture includes a spectrum allocation unit (92) for dynamically allocating spectrum to the plurality of terrestrial user devices (14-26) based on a spectral environment about the wireless access unit (12). A spectrum scan unit (60) scans the spectral environment about the wireless access unit (12) and generates a spectrum signal indicative thereof. An environment understanding unit (61) provides signal information corresponding to signal emitters in proximity to the distributed or centralized network. A spectrum table (90) assembles data related to the spectral environment and the proximity emitters for use by the spectrum allocation unit (92) in dynamically allocating spectrum.

    摘要: A communications system (100) includes a multi-rate source coder (MRSC) (102), a variable size/rate buffer (VSRB) (112), a speech buffer (104), and a buffer control block (106). The variable size/rate buffer (112) includes a source coder bit buffer (SCBB) (114) and an adaptive transmit frame buffer (116). The source coder bit buffer (114) receives speech frames coded at different rates from the multi-rate source coder (102), and deposits an integer or non-integer number of frames in the adaptive transmit frame buffer (ATFB) (116). A receiver includes a seamless rate transition module (SRTM) (308) and an variable buffer (310). The seamless rate transition module (308) correlates speech data previously coded at different rates, and it then truncates or alternatively appends, concatenates, and warps the speech data to remove any annoying artifacts at the rate change boundary.

    摘要: A communications network (10) having a plurality of wireless nodes (12-28) distributed within a region of interest makes routing decisions based on terrain information for the region of interest. A link quality determination unit (54) determines the quality of individual node-to-node links within the network (10), based on the location of the nodes (12-28) and the terrain about the nodes (12-28). A path selection unit 58 then determines an optimal path through the network 10 based on the link quality information. In one embodiment, communications corridors (102) are defined as preferred subpaths within a network for use in connecting remote nodes.
