摘要:
In a multi-user communication system, a pre-coder in a transmitter comprises a Discrete Fourier Transform (DFT) spreader configured to spread reference-signal symbols with Fourier coefficients to generate DFT-spread reference symbols. An OFDM modulator, such as an inverse-DFT, modulates the DFT-spread reference symbols onto OFDM subcarriers to produce a pre-coded OFDM transmission signal.
