Abstract
In general according to embodiments a wireless transmitter comprising a plurality of coding and modulation modules to the input information block using a coding and modulation algorithm. applying DFT processing the coded output of the modulation module of the discrete Fourier transform (DFT) precoder and the received DFT precoder of DFT output of inverse fast Fourier transform (IFFT) module the module indicated by the base station resource allocation is mapped to different subcarriers and applies IFFT processing to the DFT output. based on the output of the IFFT module output processing stage generates an output signal for wireless transmission to the wireless receiver. In different implementations the output of the coding and modulation module may be provided to IFFT module to generate output information processed by the IFFT.
In general according to an embodiment a wireless transmitter includes a plurality of coding and modulation modules to apply corresponding coding and modulation algorithms to input information blocks. A discrete Fourier transform (DFT) precoder applies DFT processing to outputs of the coding and modulation modules and an inverse fast Fourier transform (IFFT) module receives a DFT output of the DFT precoder which is mapped to different subcarriers according to the resource allocation indicated by the base station and applies IFFT processing to the DFT output. An output processing stage produces output signals based on the output of the IFFT module to transmit wirelessly to a wireless receiver. In a different implementation the outputs of the coding and modulation modules can be provided to an IFFT module to produce IFFT-processed output information.
