正交频分复用系统OFDM中的帧检测算法及其实现-Orthogonal multiplexing system split the frame in OFDM detection algorithm and its implementation

a code for fdma or frequency division multiplexing access actually a matlab code with comments so you can understand the code

OFDM is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method. A large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels.
