实信号 meaning in Chinese
real signal
Examples
- In the end , according to the relation of real number signal fft and dct , integer dct transform can been got
最后，根据实信号的fft变换和dct变换的关系，找到dct的提升矩阵，完成fft到dct的整数变换。 - Based on upper study deeply the efficient digital channelized architectures based dft polyphase filter banks to deduce and establish several kinds channelized digital receiver mathematic models for real signal
在此基础上深入研究了基于多相dft滤波器组的数字信道化高效结构,推导并建立了实信号信道化数字接收机的多种数学模型。 - A modified real signal model of channelized transmitter is presented that employs multiphase filters and discrete fourier transform to maximize computing efficiency , which can mean much in a radio communication system that requires real - time processing
特别提出了改进的实信号信道化发射机数学模型，通过利用多相滤波与离散傅立叶变换，减少信号处理运算量，这对于强调实时运行的无线通信系统有重要意义。 - Then , according to characteristic of four kinds of butterfly operation in real number signal integer fft transform keeping modulus conjugating with symmetry , different lifting matrixes has been got and real number signal integer fft transform keeping modulus conjugating with symmetry can been achieved
然后，根据实信号保持共轭对称性的fft整数变换中的四类蝶形运算特点分别构造不同的提升矩阵，从而实现实信号保持共轭对称性的fft整数变换。 - This paper particularly compares the complexities of the three manners ? the base band complex signal manner 、 the intermediate frequency complex signal manner and the intermediate frequency real signal manner , in the rf circuit and the base band digital signal processing , respectively ; chooses the intermediate frequency complex signal output manner , which not only reduces the complexity of the digital signal processing , but also be compatible with the intermediate frequency real signal output manner in some applications which have strictly request on the consistency of the amplitude and the phase in i / q channels
然而在以往的文献中很少对此进行过全面的分析。论文详细比较了三种不同的信号输出方式? ?基带复信号、中频复信号和中频实信号在rf电路和后端数字信号处理复杂度上的区别;并为接收机选择了中频复信号输出方式,在降低数字信号处理复杂度的同时,还能在某些对i / q双通道幅相一致性要求严格的应用场合兼容中频实信号输出方式。
