OFDM的原理在matalb中实现源代码，包括FFT和IFFT,加入保护间隔，循环前缀和子载波等。-Principle of OFDM is implemented in matalb source code, including FFT and IFFT, adding guard interval, cyclic prefix and sub-carrier, etc.

the code is used to show how OFDM system works and the importance of adding cyclic prefix

Matlab file for simulating a cyclic-prefix (CP) orthogonal-frequency-division-multiplexing (OFDM) system with binary phase-shift keying (BPSK) modulation on each subcarrier. CP-OFDM system includes a repetition code and interleaving across subcarrie
