摘要
正交频分复用(OFDM)是一种多载波数字调制技术,它能有效地克服传输中的多径干扰和消除码间串扰,所以在高速数据传输中得到了广泛的应用。这里将OFDM系统引入高斯白噪声信道中,实现高速数据的传输,并对误码率进行分析。
Orthogonal Frequency Division Multiplexing （OFDM） is a digital multi-carrier modulation technique Which can effectively overcome the multi-path interference in transmission and eliminate the crosstalk between codes. Therefore, it is widely used in high-speed data transmission. Here the OFDM system is introduced into the White Gaussian noise channel, thus achieving high-speed data transmission, and the analysis on the BER.
