基于 MATLAB 的伪随机序列的产生和分析
- 3GPP_LTE中OFDM和sc-ofdm 的区别,很好,容易理解解。初学者很实用
Single_Carrier_FDMA(SC-FDMA)matlab
- Single Carrier FDMA又称SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于OFDMA(主要用于下行),其最大的优势在于低峰值平均功率比(即PAPR)。本程序包括OFDMA,SC-FDE(单载波频域均衡)以及SC-FDMA程序,接收端采用经典的ZF和MMSE检测算法,程序短小精悍,相当经典,方便该领域的人学习与研究。

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,
