Electronics Design Checklist
C) 2003 Hank Wallace
This is a checklist for electronics designers. The idea is for engineers and technicians to
share experiences and create a detailed checklist, which the individual designer can pare down to meet his or her specific needs. There are many details that ...
正交频分复用(OnIlogonaJ Frequency Division Multiplexing，OFDM)技术通过将整个信道分为多个带宽相等并行传输的子信道，通过将信息经过子信道独立传输来实现通信，子信道的正交性可以保证最大限度的利用频谱资源。OFDM系统通过循环前缀来消除符号间干扰(ISI)，通过IDFT/DFT调制解调降低了系统实现的复杂度。由于其频谱利 ...
