由接收器检测符号的方法、接收器及仪表
摘要：
一种检测符号的技术，包括：对包括至少两个重复符号的接收信号执行过尺寸离散傅里叶变换(DFT)操作(704)。基于所述DFT操作确定一个或多个可能符号的子载波的信号特性的和(706)。基于所述DFT操作确定所述一个或多个可能符号的非子载波的信号特性的和。最后，基于所述子载波的信号特性的和与所述非子载波的信号特性的和确定是否检测到所述一个或多个可能符号的一个或多个(710)。
摘要（英）：

A technique for detecting symbols includes performing an over-sized discrete Fourier transform (DFT) operation on a received signal that includes at least two repeated symbols (704). A sum of energies for subcarriers of one or more possible symbols are determined based on the DFT operation (706). A sum of energies for non-subcarriers of the one or more possible symbols is determined based on the DFT operation (708). Finally, a determination (710) is made as to whether one or more of the one or more possible symbols is detected based on the sum of signal characteristics for the subcarriers and sum of signal characteristics for the non-subcarriers.
