    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).

    摘要: The present invention relates to signal transmitting/receiving apparatuses. The signal transmitting apparatus includes an inverse discrete Fourier transform module, a cyclic prefix adding module, a preamble adding module, and a digital-analog converting module. The inverse discrete Fourier transform module receives modulated data, performs inverse discrete Fourier transform, and generates a first symbol. The cyclic prefix adding module adds a predetermined cyclic prefix to the first symbol, and generates a second symbol. The preamble adding module adds a predetermined preamble to the second symbol, and generates a third symbol. The digital-analog converting module converts the third symbol including the cyclic prefix and the preamble into an analog symbol.
