Q_DSSS
直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。(DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.)

LFM_BC
一种基于LFM和Barker码复合调制的雷达波形，理论上分析了该低截获雷达波形的组成。通过仿真得到复合调制信号的时域波形、频谱图和模糊函数图，与LFM信号和Barker码信号对比分析对复合调制雷达信号的距离和多普勒模糊函数、截获因子等进行了研究。(A radar waveform based on LFM and Barker code modulation is presented. The composition of the waveform is analyzed theoretically. The time domain waveform, spectrum and ambiguity function of the compound modulation signal are obtained by simulation. The range and Doppler ambiguity function and interception factor of the compound modulation radar signal are studied by comparing with LFM signal and Barker code signal.)
