Abstract: Lossless compression of fragmented image data is disclosed. In some embodiments, a stream of information comprising data elements having statistical characteristics is received. An encoded output is produced by an encoder comprising a data compressor that implements a variable length code that is adapted to the statistical characteristics of the data elements. The output and information from which the variable length code can be derived are stored.

Abstract: Lossless compression of fragmented image data is disclosed. In some embodiments, a stream of information is received, wherein the stream of information comprises a sequence of tuples and wherein each of the tuples comprises data elements corresponding to one of a plurality of input channels. A channel transformer is employed to rearrange the data elements into a plurality of output channels for an output stream wherein the output channels have higher compressibility than the input channels. The compressed output stream is stored.

Abstract: Format identification for fragmented data is disclosed. In some embodiments, an input stream of information that is divided into fragments is received. Fragment boundaries are determined and a data format for each fragment is found based on continuity properties including by: dividing the stream of information into windows, determining whether each window has a known or unknown format; and comparing portions of windows having an unknown format with neighboring windows to determine fragment boundaries. The stream of information is compressed using a compression technique selected based on the data format, and the compressed stream is stored.

Abstract: Format identification for fragmented data is disclosed. In some embodiments, an input stream of information that is divided into fragments is received. Fragments are determined and a data format for each fragment is found based on continuity properties including by: determining a physical to canonical layout transformation, determining a tuple size, and partitioning bit positions in tuples into disjoint groups wherein each group corresponds to a channel. The stream of information is compressed using a compression technique selected based on the data format, and the compressed stream is stored.

Abstract: Format identification for fragmented data is disclosed. In some embodiments, an input stream of information that includes a continuity property is received. A format identifier of at least a portion of the stream is determined, wherein the format identifier includes a data representation size, a group size, and an alignment that is consistent with the continuity property. The stream of information is compressed using a compression technique selected based on the format identifier to produce a compressed stream, and the compressed stream is stored.

Abstract: Systems and methods are disclosed which provide aggressively sculpted or shaped antenna beams, such as sector antenna beams, for use in communication networks. Preferred embodiments use passive antenna feed networks, preferably configured as personality modules, which are adapted for corresponding topological and morphological features. Preferred embodiment feed networks may be coupled to linear or curvilinear antenna arrays to provide antenna beams having a desired contour. Using the disclosed systems and methods path loss variance is minimized for improved system capacity and/or signal quality. Moreover, the disclosed systems and methods provide for reduced average transmission power levels further allowing increased capacity and/or signal quality.
