  • Publication number: 20020129314
    Abstract: A QCTC (Quasi-Complementary Turbo Code) generating apparatus having: a turbo encoder for generating an information symbol sequence and a plurality of parity symbol sequences by encoding the information symbol sequence; a channel interleaver for individually interleaving the symbol sequences, generating new parity symbol sequences by multiplexing the symbols of parity symbol sequences with the same priority levels, and serially concatenating the information symbol sequence and the new parity symbol sequences; and a QCTC generator for generating a sub-code with a given code rate by recursively selecting a predetermined number of symbols from the concatenated symbol sequence at a given starting position.

  • Publication number: 20020114401
    Abstract: An apparatus generates quasi-complementary turbo codes in a communication system. The apparatus includes a turbo encoder, an interleaver for interleaving symbols output from the turbo encoder according to a give rule, and a code generator for generating the quasi-complementary turbo codes by puncturing and repeating the interleaved symbols from the interleaver. Further, an apparatus decodes quasi-complementary turbo codes in the communication system. The decoding apparatus includes a code decoder for generating code symbols according to a code rate transmitted through depuncturing sub-codes of quasi-complementary turbo codes transmitted from a transmitter and soft combining the sub-codes, a deinterleaver for deinterleaving the symbols output from the code decoder, and a turbo decoder for decoding an output of the deinterleaver.

  • Publication number: 20020039355
    Abstract: A communication method in a mobile communication system in which an access terminal transmits to an access network DRC information indicating a selected one of forward data rates requested by the access terminal is provided. The access network designates a DRC information length DRC Length indicating a number of slots where the DRC information is repeated and transmits the designated DRC information length to the access terminal. The access terminal gates transmission of DRC information to the access terminal at one time slot in every DRC information length received from the access network.

  • Patent number: 6256488
    Abstract: A method for processing a dialed signal in a WLL terminal. Upon sensing of an off-hook state of a telephone connected by wires to a WLL terminal, a DTMF signal corresponding to a key input from the telephone is generated and it is converted into a digital signal. If the digital signal is not a predefined specific key, the digital signal is stored in a dial buffer. If the digital signal is a predefined specific key, the DTMF signal corresponding to the digital signal stored in the dial buffer is sequentially generated to be radio-transmitted.
