频带分割 meaning in Chinese

band sharing
band splitting

We design the qmf based on the criteria of minimum frequency bandwidth and the qmf that possess linear phase , and give a example of a signal decomposed and restructured . 4 . in the research of channel dropping filters , we use 5 rank butterworth filter to approach the digital filter . we design lc unpower netwok and rc power network . we manufacture lc lowpass and highpass filter ， and test their performance ; we simulate the appliance of the channel dropping filters in the system
4 .在频带分割滤波器的设计方法中，用5阶巴特沃斯滤波器逼近最小频宽正交镜像滤波器，对无源和有源滤波器进行了仿真设计；设计并制作了无源lc低通和高通滤波器，测试了它们的性能；并对分割滤波器在系统中的应用进行了计算机仿真。
However , the paralleling communication can meet the requirements of high speed and fidelity in underwater signal transmissions . ofdm is a kind of novel paralleling transmission technology . the principle of ofdm is that the whole bandwidth can be divided into some subchannels , the high - speed serial signal stream is modulated by some orthogonal subcarriers
正交频分复用( ofdm )是近年来数字通信中流行的一种并行传输新技术，其核心思想是将整个可用频带分割成多个正交子信道，将待传输的高速串行码流并行的调制在这些子信道载波上。
