| 摘 要： | 提出了博斯-查德胡里-霍昆格母（BCH）码新的编码和解码方法,通过纠正t（t≥2）个错误,达到提高系统的抗干扰能力和克服信道衰落的影响,提高了编译码速度。在无多径加性高斯白噪声（AWGN）信道情况下,仿真并比较了不同信噪比（SNR）下BCH编码和重复编码传输PPM-TH-UWB超宽带信号和PAM-DS-UWB超宽带信号的误码率,并画出了误码率曲线。通过计算机仿真,证明在AWGN信道情况下,BCH编码在传输超宽带信号时能获得较低的误码率。

| Abstract: | A new coding and decoding method of Bose-Chaudhuri-Hocquenghem （BCH） is proposed which can speed up the computation of coding and decoding as t error correction t （t≥2） code to obtain high capacity and resist the fatal transmission error when communications are carried on Additive White Gaussian Noise （AWGN） channel. The comparison of BER of BCH code and code-repetition codes are given for transmitting PPM-TH-UWB signal and PAM-DS-UWB signal on different signal to noise ratio, and the simulation results are given. It can be concluded that the BCH code has better error correcting ability. |
