A subscriber station is provided for use in a wireless network communicating according to a multi-carrier protocol, such as OFDM or OFDMA. The subscriber station comprises: a size M1 Fourier Transform (FT) block that receives input symbols and generates M1 FT pre-coded outputs; a size M2 Fourier Transform (FT) block that receives input symbols and generates M2 FT pre-coded outputs; and a size N inverse Fourier Transform (IFT) block that receives N inputs, including the M1 FT pre-coded outputs and the M2 FT pre-coded outputs, and generates N outputs to be transmitted to a base station. The FT blocks are Fast Fourier Transform blocks or Discrete Fourier Transform blocks. The IFT block is an inverse Fast Fourier Transform block or an inverse Discrete Fourier Transform block.
