中文说明：该程序给出了使用梳状导频信号的 OFDM 系统的仿真研究。在程序启动与生成二进制随机数作为源。然后，进行 bpsk 调制。信道矢量是使用 rand 函数生成的。符号透过这个 channel.at 的 bpsk 接收器，信号解调，确定符号错误概率。然后，经过 bpsk 解调误码概率确定。
English Description：
The program gives the simulation of OFDM system using Comb pilot signal.The program starts with the generation of random binary numbers as source. then, bpsk modulation is done.A channel vector is generated using rand function. the bpsk symbols are transmitted through this channel.at the receiver, the signal is demodulated and symbol error probability is determined. then, after bpsk demodulation, the bit error probability is determined.
