相对完整的OFDM通信系统的仿真设计
- 一个相对完整的OFDM通信系统的仿真设计,包括编码,调制,IFFT, %上下变频,高斯信道建模,FFT,PAPR抑制,各种同步,解调和解码等模 %块,并统括系统性能的仿真验证了系统设计的可靠性。
OFDM
- 数,都需要通过导频序列来获取同步信息,而且为了达到更好的均衡效果,OFDM 系统也要进行简单的频域均衡。此外,OFDM与SC.FDE的帧格式也十分相似,都 需要添加CP(SC.FDE采用UW)来吸收前面帧的干扰并满足循环卷积特性。 由于OFDM在结构和原理上都与SC.FDE十分相近,可以设计一种双模式系统。 双模式系统仅仅改变IFFT模块在发送端和接收端的位置就可以同时支持两种系统传 输。两种系统都可以通过编码、自适应调制和空间分集提高性能。而且,
