PN4
- 语言:VHDL 功能:该PN4序列的特点为将一个4位序列的前两位取异或,再让序列左移一位,用异或的结果作为序列的最后一位。序列周期是15,即15位伪随机序列。其中包括序列的产生模块和检测模块。对于误码检测,首先捕获相位。然后,规定测试的码的总个数,统计这些码中有多少个不能满足PN序列特点的,用计数器统计个数。如果发现误码过多,可能是相位失调,重新捕获相位,再进行误码检测。 仿真工具:modelsim 综合工具:quartus -Language: VHDL function:

- 直接序列扩频系统(DS,Direct Sequence)又称为直接序列调制系统或伪噪声系统(PN 系统),简称为直扩系统,是目前应用较为广泛的一种扩展频谱系统。要传送的信息经伪随机序列编码后对载波进行调制。在发信端越冬用扩频序列去扩展信号的频谱,在收信端,用相同的扩频友序列进行解扩,将展宽的频谱扩展信号还原成原始信号。因为伪随机序列的速率远大于要传送信息的速率,所以受调信号的频谱宽度将远大于要传送信息的频谱宽度,帮称之为扩频-Direct sequence spread spectrum (DS
