In this paper the 16 QAM (M=16) Modulator is simulated for OFDM using MATLAB tools. In 16QAM, BER performance is better than 64 QAM [2], [3]. OFDM (Orthogonal Frequency Division Multiplexing) is technology that will certainly play a vital role in next generation wireless communication ...

无论是《MIMO-OFDM无线通信技术及MATLAB实现》还是《Simulation and Software Radio for Mobile Communications》,均没有我上面疑问的答案。 在仿真中是否需要我这么考虑,我也不确定,造成的结果也是实验曲线会相比理论有一定的平移。 四、总结 自本科听说过OFDM、信道估计、均衡等概念,到前段时间开始思考如何用MATLAB来仿...
在给出OFDM系统模型的基础上,用MATLAB语言实现了传输系统中的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,研究保护时隙、循环前缀、信道采用LS估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。 关键词:正交频分复用;仿真;循环前缀;信道估计 MATLAB Simulation and Performance Analysis of ...
测量的性能相对于误码率和信噪比,并使用MATLAB实现。 其余部分被组织为MIMO-OFDM [II],其给出了所实现的系统的图片,随后是信道[III]和调制技术[IV]。这是随后提出的工作[V]。其描述了不同的信道模型和调制方案。 二、 MIMO- OFDM a. OFDM OFDM是一种多载波传输技术,其中频带被离散成多个子信道。通常的...
