Abstract: A method of transmitting data may include converting a stream of serial data bits into a set of parallel quadrature amplitude modulation (QAM) symbols. The method may additionally include applying a partial discrete Fourier transform-spread technique to transform a block of low-frequency subcarriers into a single-carrier QAM signal. The single-carrier QAM signal may bear information of a first subset of QAM symbols from the set of parallel QAM symbols. The method may additionally include transforming one or more remaining QAM symbols to form one or more subcarriers. Each of the one or more subcarriers may bear information of a corresponding QAM symbol from the one or more remaining QAM symbols. The method may additionally include generating a hybrid signal that includes the single-carrier QAM signal and the one or more subcarriers. The method may additionally include transmitting the hybrid signal.
Abstract translation: 传输数据的方法可以包括将串行数据比特流转换成一组并行正交幅度调制（QAM）符号。 该方法可以另外包括应用部分离散傅里叶变换扩展技术来将低频子载波块变换为单载波QAM信号。 单载波QAM信号可以承载来自该组并行QAM符号的QAM符号的第一子集的信息。 该方法可以另外包括变换一个或多个剩余的QAM符号以形成一个或多个子载波。 所述一个或多个子载波中的每一个可以承载来自所述一个或多个剩余QAM符号的相应QAM符号的信息。 该方法还可以包括生成包括单载波QAM信号和一个或多个子载波的混合信号。 该方法可以另外包括发送混合信号。
