    摘要： A device and method for generating and distributing convolutional codes such that performance degradation due to a bad link environment may be minimized during channel decoding in a CDMA communication system. The convolutional encoder encodes transmission data at a coding rate of R=1/6 and can be used for a channel encoder. Such a channel encoder can be used in both a DS-CDMA communication system and a multicarrier CDMA communication system. When the channel encoder is used in the multicarrier CDMA communication system, the symbols outputted from multiple constituent encoders for the channel encoder are distributed to multiple carrier channels according to a predetermined rule, and the constituent encoders for the channel encoder can minimize the performance degradation of the overall channel encoder even though an output of a particular constituent encoder is completely off at the transmission channel.

    摘要： Disclosed is a power control method for a mobile station which has at least one compressed mode frame. A compressed mode frame includes a data transmission duration where data is transmitted at a first frequency, and a data transmission-off duration where a second frequency is searched to perform an inter-frequency handoff to the second frequency. The transmission power during the data transmission duration is increased to compensate for the loss of transmission power during the data transmission-off duration. In the method, a base station sets a power control threshold depending on the length of the data transmission-off duration. The base station receives transmission power-increased data and compares the received power of the data signal with the power control threshold. The base station generates a power-up command when the power control threshold is higher than the receiving power, and generates a power-down command when the power control threshold is lower than the receiving power.

    摘要： A subframe data transmission device for a mobile communication system. A bit generator generates specific bits having a predetermined value. A bit inserter segments a received data bit stream into at least two subframes, and inserts the generated specific bits at locations where an error probability is higher in the respective subframes. A turbo coder codes the subframe data comprised of the data bit stream and the specific bits. The subframe is equal in size to an ARQ (Automatic Repeat Request) block, and the specific bits are inserted at a rear portion of the subframe. The bit inserter includes a delay for delaying the received data bit stream by the number of the specific bits to be inserted; and a selector for connecting, upon completion of receiving data bits for the subframe, the received data bits to the delay and applying an output of the bit generator to the turbo coder; and applying, when the specific bits are inserted, an output of the delay to the turbo coder.

    摘要： An apparatus and method for determining feedback information detection in a broadband wireless communication system are provided. In the detection determining apparatus, a demodulator correlates each of tiles carrying received feedback information with an orthogonal vector including a pilot symbol in each possible codeword, each tile being a predetermined number of subcarriers, and calculates the squares of the absolute values of the correlations. A codeword correlation calculator sums the squares of the absolute value of the correlations of the tiles for each possible codeword. A detection decider determines whether to perform detection on the feedback information based on the maximum of the sums.
