    摘要： Provided is a base station. The base station includes a transceiver, a frequency allocation unit, and an orthogonal code allocation unit. The transceiver communicates with a terminal. The frequency allocation unit allocates a frequency resource to the terminal through the transceiver. The orthogonal code allocation unit generates an orthogonal code index table including a plurality of orthogonal code combinations, and allocates one of the orthogonal code combinations included in the orthogonal code index table to each terminal, to which the frequency resource has been allocated for a service request of the terminal, through the transceiver not to multiply be allocated. At least one of a plurality of orthogonal codes included in the orthogonal code combination is orthogonal to at least one of a plurality of orthogonal codes included in an orthogonal code combination allocated to another terminal.

    摘要： Provided are a high-speed Discrete Fourier Transform (DFT) apparatus and a method thereof. The high-speed DFT apparatus includes a zero padding unit, a Fast Fourier Transform (FFT) unit, and a preamble index decision unit. The zero padding unit receives a first input signal having a length of a prime number and changes the first input signal into a second input signal having a length of an exponentiation of 2. The FFT unit performs a FFT on the second input signal outputted from the zero padding unit. The preamble index decision unit detects a preamble index from an output signal from the FFT unit.

    摘要： Provided are an apparatus and a method for tail biting convolutional encoding. The apparatus includes a plurality of shift registers and at least one operator. The plurality of shift registers sequentially performs a shift operation on input bit-stream. The operator outputs an encoded bit-stream by performing convolutional encoding on an output of the shift register using a generator polynomial corresponding to a predetermined code rate. A transmission encoded bit-stream is created by replacing encoded data for a certain initial bit-stream of the encoded bit-stream with a bit-stream obtained by subsequently performing convolutional encoding on the initial bit-stream.
