OFDM is multicarrier modulation (MCM) technique which provides an efficient means to
handle high speed data streams on a multipath fading environment that causes ISI. Normally
OFDM is implemented using FFT and IFFT’s. To decrease the BW waste bro

程序实现的主要功能：
OFDM调制识别：研究了基于高阶累量和基于小波变换的OFDM信号和单载波调制信号的识别算法，仿真分析了两种算法在高斯信道和多径瑞利衰落信道下的信号识别性能。
OFDM参数估计：研究了基于Welch算法和AR模型法求解功率谱进而估计信号带宽的算法，对两种算法的估计性能进行了比较；根据OFDM信号的循环平稳性研究了基于循环谱的载频估计算法；根据 OFDM信号的自相关性研究了基于可变延时自相关和固定延时自相关的FFT相结合的算法，估计了OFDM信号的有效数据长度、符号
