处理用于无线传输的信息块
摘要：
公开了处理用于无线传输的信息块。种无线通信系统包括移动设备,包括:多个编码与调制模块,其生成经调制的输出,为了生成经调制的输出,每个编码与调制模块将相应编码与调制算法应用于相应的对应输入信息块;离散傅里叶变换DFT预编码器,其生成DFT输出,为了生成DFT输出,其对每个经调制的输出应用DFT处理;反向快速傅里叶变换IFFT模块,被配置为接收所述DFT输出,并且生成对应的IFFT输出,其中所述IFFT输出中每个IFFT输出对应于相应编码与调制算法,为了生成所述IFFT输出,IFFT模块对每个相应DFT输出应用IFFT处理;以及输出处理阶段,基于IFFT输出而产生输出信号来无线地传输到无线接收器。
摘要（英）：

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.
