中文说明：
OFDM调制测试：这是一组关于COFDM（编码正交频分复用）和卷积、BCH、Reed-Solomon（RS）和低密度奇偶校验（LDPC）等编码方案的五（5）个代码。研究了一个正交频分复用（OFDM）信号在高斯白噪声信道下的传输特性，并计算了其误码率。
English Description：
Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.
