Patent ID: 7787546

Claim:
For use in a wireless network, a subscriber station capable of communicating with the wireless network according to a multi-carrier protocol, the subscriber station comprising: a size M Fourier Transform (FT) block capable of receiving input symbols and generating therefrom M FT pre-coded outputs, the input symbols comprising data signals and pilot signals; and a size N inverse Fourier Transform (IFT) block capable of receiving N inputs, the N inputs including the M FT pre-coded outputs from the size M FT block, and generating therefrom N outputs to be transmitted to a base station of the wireless network, wherein the size M FT block and the size N IFT block are one of: 1) a Fast Fourier Transform (FFT) block and an inverse Fast Fourier Transform (IFFT) block; and 2) a Discrete Fourier Transform (DFT) block and an inverse Discrete Fourier Transform (IDFT) block, wherein the data signals and pilot signals are mapped to alternating subcarriers and the size N IFT block receives signaling and control information on at least some of the N inputs other than the M FT pre-coded outputs.
