  • Publication number: 20060156172
    Abstract: An apparatus and method interleaving symbols coded by a turbo encoder in a communication system that uses the turbo encoder for encoding transmission information into coded systematic symbols and at least one parity symbol pair, and maps the coded symbols using a second or higher modulation order before transmission. An interleaver controller performs a control operation of cyclic-shifting the systematic symbols among the symbols coded by the turbo encoder depending on a size of a physical packet to be transmitted, the number of transmission slots, and the modulation order, using an equation of (K×c+k) mod R, and cyclic-shifting redundancy symbols constituting the remaining size of the coded symbols to be transmitted, using an equation of floor{(K×c+k)/D}mod R. An interleaver cyclic-shifts input symbols under the control of the interleaver controller.

  • Publication number: 20060120270
    Abstract: An apparatus and method transmits a packet data symbol in a high-rate packet data (HRPD) mobile communication system for broadcasting service. A transmission processor generates a modulated symbol by encoding, interleaving and modulating a physical layer packet to be transmitted, and arranges the modulated symbol in a data tone. A tone inserter inserts a guard tone and a pilot tone into the data tone. A tone power allocator sets a different pilot-to-data tone power ratio according to a position of a slot, in which the packet data symbol is included, and allocates power according to the pilot-to-data tone power ratio. A transmitter transmits the packet data symbol.

  • Publication number: 20060098569
    Abstract: An apparatus and method are provided for arranging tones to isolate signals between base stations (BSs) in a high rate packet data (HRPD) system. Packet data is received from a higher layer and the received packet data is channel-coded and modulated. Guard tones are inserted into symbols of the modulated packet data. Pilot tones are inserted using pilot tone arrangements based on preset pilot tone offsets. The packet data symbols to which the pilot tone arrangements have been applied are spread such that BSs for transmitting different broadcast contents are distinguished from each other. A cyclic prefix (CP) is inserted after performing an inverse Fourier transform on the spread packet data symbols, and the symbols are transmitted.
