PN Sequence Generator模块的参数包括Sample time和Output port sample time。 Sample time参数用于设置PN序列基带信号的码元速率。如果设置Sample time为0.01,则产生PN序列基带信号的码元速率为100 baud,采样速率为100 Hz。 Output port sample time参数则用于设置两个速率转换器模块的输出基带信号和BPSK信号的采样速率。
The output of the pseudorandom number sequence generator is then logically combined with the incoming data to provide scrambled data, simplifying the complexity of the encoder or decoder significantly.Weldon Edward J. Jr.

发端PN码的产生可直接选用通信模块库中PN Sequences Generator,参数generator polynomial设为E100l 01]。参数initial states可任意设定,只要不是全零即可。参数Sample time设为0.001s。 乘法器、积分器模块用于获得收、发两端信号的相似性度量。比较器的门限值设为PN码周期的一半,即0.031/2S。 图3模型工作过程如下:...
An M-sequence generator has a linear feedback shift register, a mask table, a masked operation circuit, and a control unit. The mask table stores mask data corresponding to different phase shifts. The masked operation circuit performs logic operations on the mask data and the contents of the ...
A pseudorandom number sequence generator comprises a bidirectional shift register arranged to be loaded with a multi-bit sequence. The shift register is responsive to an ith clock pulse and an ith direction control bit for shifting the multi-bit sequence in one of two directions, delivering an ...
