WebThe OFDM scheme differs from traditional FDM in the following interrelated ways: 1. Multiple carriers (called subcarriers) carry the information stream, 2. The subcarriers are orthogonal to each other, and. 3. A guard interval is added to each symbol to minimize the channel delay spread and intersymbol interference.

为什么OFDM在调制时是IFFT解调才是FFT_百度知道

Web16 apr. 2024 · OFDM combines the benefits of Quadrature Amplitude Modulation (QAM) and Frequency Division Multiplexing (FDM) to produce a high-data-rate communication system. QAM refers to a variety of specific modulation types: BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), 16QAM (16-state QAM), 64QAM (64-state … Webofdm是一种多载波调制方案，它的基本原理是将传输信道分解为若干个正交的子信道，将需要传输的高速数据信号转换为并行的低速数据流，并调制到每个正交信道的子载波上进行传输，叠加传输的若干正交信号在接收端通过一定方式进行解调分离。 Webofdm为什么要用到ifft/fft，首先得理解ofdm的基本原理。 早期产生ofdm信号是使用一组相互正交的载波源，使得调制到载波上的符号相互正交，这是一种模拟域实现ofdm调制的方法。 而ifft可以在数字域中实现ofdm信号的调制保证输出ofdm信号的各子载波间相互正交，ofdm技术具有强大的数字信号处理能力。 5 评论 分享 举报 dyson airwrap styler where to buy
