    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: A quadri-filar helical antenna structure includes a cylindrical body having a relative dielectric constant greater than 4, and four radial metal plates on a distal end of the cylindrical body, and each radial metal plate is extended along the cylindrical body. The ends of every two adjacent radial metal plates are connected to form two antenna structures, and a circuit board is fixed. A ground surface is installed on one side of the circuit board and coupled to one of the antennas. An impedance matching circuit is installed on another side of the circuit board, and one end of the impedance matching circuit is coupled to another antenna. A feeder is installed at another end of the impedance matching circuit. Four radial metal plates having an electric length about odd multiples of a quarter of wavelength of the cylindrical body can receive satellite signals.
