线性调频信号在宽脉冲内附加线性调频以扩展信号频带，提供了时宽带宽积大于1的信号，有效地解决了大的时宽和带宽不可兼得的矛盾。-LFM pulse width within the additional chirp signal bandwidth expansion, Broadband provides a wide plot when more than one signal, effectively solve the big time and wide bandwidth closest

该程序实现了chirp信号的二进制调制及匹配滤波解调，并且求解出了调制的chirp信号通过AWGN信道后的误码率 (The program realizes the chirp signal binary modulation and matched filter demodulation, and the solution of the chirp signal through the AWGN channel after the error rate)
