pseudo random coding meaning in English
伪随机码
Examples
- This scheme can also adapt ds / dmpsk modulation and demodulation with different base data rate , different pseudo random codes and different intermediate frequency
该方案可以适应不同基带数据速率、不同伪随机码和不同中频的ds / dmpsk的调制和解调。 - This dissertation adopts a universal digital ds / dmpsk modulation and demodulation scheme which is based on fpga . this scheme adopts quadrature balanceable modulation , intermediate frequency sampling , digital matched filtering , delay differential demodulation techniques and so on . it directly processes the digital signals on intermediate frequency without down - conversion , and doesn ’ t need pseudo random codes synchronization and carrier wave extraction circuits
本文采用了一种基于fpga的通用数字调制解调方案,该方案在调制端采用了正交平衡调制技术,在解调端采用了中频带通采样、数字匹配滤波、延时差分解调等技术,直接在中频上进行数字信号处理,不需要进行下变频,也不需要增加额外的伪随机码同步捕获和载波提取电路。
