Title: Dual-/multi-band planar inverted-F antenna and its radiating patch
Inventor: LIN YEH-CHIAN
IPC: H01Q9/00
Filed: 2002-03-29
Granted: 2003-02-01
Abstract: This invention provides a dual-/multi-band planar inverted-F antenna (PIFA) and its radiating patch suitable for GSM/DCS or GSM/DCS/PCS operations. The proposed radiating patch comprises a ground point, a feed point and two slits. The said two slits are inserted at the edge of the said radiating patch and extended into the interior of the said radiating patch. Owing to the said two slits, a single meandered current path is formed in the said radiating patch, and the said current path controls the two operating frequencies (one lower frequency and one higher frequency) of the said PIFA. The length of the said current path equals to about one-quarter wavelength of the lower frequency and also equals to about one-half wavelength of the higher frequency. In addition, when a smaller sub-patch is added to the said radiating patch, the impedance bandwidth of the higher frequency can be greatly enhanced, which makes the said PIFA capable of GSM/DCS/PCS multi-band operations.

Title: Methods and apparatus for decoding LDPC codes
Inventor: RICHARDSON TOM
IPC: H03M13/00
Filed: 2002-06-07
Granted: 2007-07-21
Abstract: Methods and apparatus for decoding codewords using message passing decoding techniques which are particularly well suited for use with low density parity check (LDPC) codes and long codewords are described. The described methods allow decoding graph structures which are largely comprised of multiple identical copies of a much smaller graph. Copies of the smaller graph are subject to a controlled permutation operation to create the larger graph structure. The same controlled permutations are directly implemented to support message passing between the replicated copies of the small graph. Messages corresponding to individual copies of the graph are stored in a memory and accessed in sets, one from each copy of the graph, using a SIMD read or write instruction. The graph permutation operation may be implemented by simply reordering messages, e.g., using a cyclic permutation operation, in each set of messages read out of a message memory so that the messages are passed to processing circuits corresponding to different copies of the small graph.
