    摘要: A parity-check-code decoder is adapted for receiving a channel quality ratio and at least (N) bits that are to be decoded. The parity-check-code decoder treats each of the bits as a bit node, and includes: a verifying circuit that multiplies (N) bit nodes by a matrix to obtain (N-K) check nodes; a reliability-generating circuit that generates a reliability index that serves as an extrinsic check index for each of the bit nodes to transmit to the check nodes; a bit exchange circuit that generates an extrinsic bit index for each of the check nodes to transmit to the bit nodes; a check-exchange circuit that updates a plurality of the extrinsic check indices based on the extrinsic bit indices for the bit nodes to transmit to the check nodes; and a reliability-updating circuit that updates the reliability index of and determines an updated value for each of the bit nodes.

    摘要: The present invention discloses a quadri-filar helix antenna structure, which comprises a cylindrical body made of a dielectric material with a relative dielectric constant ∈r greater than 4, and four radiating metal plates disposed on a distal end surface of the cylindrical body and extended along the radial direction of the center of the cylindrical body to its periphery and then along the radial direction in a spiral course on the circumferential surface thereof to its periphery on the other end respectively, wherein the ends of every two adjacent radiating metal plates are coupled with each other to constitute two sets of antenna structures, a penetrating hole is disposed at the central position of the cylindrical body and is precisely embedded into a coaxial cable, and a shield cable disposed at the periphery on one end of the coaxial cable is coupled to an end of another set of antenna structure. Therefore, the antenna not only reduces the overall volume, but also greatly lowers its production costs.

The procedure of the bounded distance decoding is simplified and the number of correlation calculating is reduced via a set of pre-established XOR masks. The decoding method includes: picking up the source code part of the received message; executing a XOR calculating for the source code part with the XOR masks, and encoding the results thereof to produce a set of compared codes; executing a correlation calculating for the set of compared codes and the received message; and determining a compared code having the maximum correlation result as the decision.
