摘要： Provided is a decoding apparatus and method using orthogonal space-time block codes (OSTBCs) robust against timing errors. The decoding apparatus may include: a cyclic prefix removal unit to receive a signal, and to remove a cyclic prefix in the signal; an inverse discrete Fourier transform (IDFT) unit to apply an IDFT to the signal with the removed cyclic prefix; a guard band removal unit to remove a guard band in the inverse discrete Fourier transformed signal, and to generate a complex matrix; a channel estimation unit to transmit a carrier corresponding to the complex matrix and channel status information associated with transmit and receive antennas; and a decoder to calculate a channel status vector with respect to a complex symbol included in the complex matrix, using the channel status information, and to calculate an inner product between the channel status vector and the complex matrix, to restore the complex symbol.

摘要： Provided are a method and apparatus for transmitting control information and packet data. The method includes generating control channels which transmit the control information; generating control indication channel which indicates whether the control channels are transmitted or not; generating data channels in order to transmit the packet data based on the control information; multiplexing the control channels, the control indication channels, and the data channels; and transmitting the control channels, the control indication channels, and the data channels. According to the present invention, when control information and packet data are transmitted in downlink, by transmitting additional information indicating whether control channels are transmitted or not, resources not actually allocated to control channels can be allocated to data channel and the mobile station can receive data channel using the control indication information.

摘要： Provided are a fixed station receiver for a Multi-Input Multi-Output (MIMO) communication system and an uplink adaptation method thereof. In the uplink adaptation method, a sounding reference signal (SRS) is received from a terminal including a plurality of transmission antennas. A complex channel matrix (H) corresponding to a channel response and a noise variance (σ2) corresponding to a noise power is calculated from the sounding reference signal. A signal-to-interference and noise ratio (SINR) on each transmission symbol is calculated with reference to the complex channel matrix (H) and the noise variance (σ2). A pre-coding matrix of the terminal is selected with reference to the signal-to-interference and noise ratio (SINR).
