Qam调制部分原理框图 - The second part studies the characteristics of cdma2000 1x reverse link , and implements a softcore design of the cdma20001x rtl soc with hdl ( hardwire desciptionin language ) verilog in accordance with the is - 2000 specifications . the model include the softcore of a spread spectrum modulation and a simple 8 - bit processor . as the same time simulate all the parts of the soc softcore with software modesim
，本文的第二部分认真的研究了cdma20001x的反向链路的特点，设计反向链路的扩频调制片上系统方案。用硬件语言verilog设计cdma20001x的扩频调制片上系统的ip软核。其中包括扩频调制部分和一个8位的cpu设计。 - The whole pwm circuit contains two subcircuit , the front - end is pwm module that make up of the counter that based on nine mosfet true - single - phase - clock d flip - flop ; the back - end is demodulated module , which is consist of a three order chebyshev low - pass filter used trans - conductor capacitor . all the subcircuits are simulated . at last , an approving simulated result of the whole circuit is given too
在调制部分,利用九管单相时钟d触发器构成计数器,并由此组成了脉冲宽度调制电路,同时给出了在典型温度下的仿真结果;在解调部分,介绍了低通滤波器从无源到有源的设计方法,设计了三阶切比雪夫低通跨导电容滤波器,同样给出了相应的仿真结果;最后,作为将脉冲宽度调制电路和滤波器作为整体电路,以脉冲调频波为输入进行了仿真,取得了令人满意的结果。 - With the increasing requirements for detecting distance , photoelectric module , including light source and modulation , can be put under water to reduce the loss of light power in the optical fiber transmission and transmit the detected signal to the signal processing workstation on the shore . optical transceivers must be applied to realize the low - rate optical communication between the workstation on the shore and the long - distance photoelectric modules under water
随着光纤水听器阵列技术的发展,可将光源与调制部分作为远程光电模块置于水下,减少光纤传输过程中光波信号的损耗,而直接将光纤的探测信号传回岸基工作站进行处理,以增加光纤水听器的探测距离。 - After describing channel coding and modulation system based on cofdm transmission scheme , we study the methods of circuit design in all blocks , including front control , randomization , reed - solomon code , outer interleaving , inner interleaving , mapping and frame shaping
