Patent ID: 8817590

Claim:
A wireless transmitter comprising: a plurality of coding and modulation modules configured to generate a plurality of modulated outputs, wherein to generate the plurality of modulated outputs, each coding and modulation module is configured to apply a respective coding and modulation algorithm to a respective corresponding input information block of a plurality of input information blocks; a discrete Fourier transform (DFT) precoder configured to generate a plurality of DFT outputs, wherein to generate the plurality of DFT outputs, the DFT precoder is configured to apply DFT processing to each respective modulated output of the plurality of modulated outputs; an inverse fast Fourier transform (IFFT) module configured to receive the plurality of DFT outputs, and generate a plurality of IFFT outputs, wherein each IFFT output of the plurality of IFFT outputs corresponds to a respective coding and modulation algorithm and is mapped onto a different respective portion of a wireless spectrum, wherein to generate the plurality of IFFT outputs, the IFFT module is configured to apply IFFT processing to each respective DFT output of the plurality of DFT outputs; and an output processing stage to produce output signals based on an output of the IFFT module to transmit wirelessly to a wireless receiver.
