差分解调 meaning in English
differential demodulation
Examples
- In the third part , a new adaptive trellis coded modulation ( atcm ) solution was presented . we analysis the best coding scheme in different channel modes , different snr and different demodulation solution
仿真结果表明，在解调观测长度相同的情况下，其性能和多码元差分解调方式大致相同，但大大简化了接收机结构。 - It need n ' t to distill coherent carrier and there is no trouble such as phase faintness , loop hit etc . the packaged wave of n / 4dqpsk is comparatively tiny , which is appropriate to the mobile communication
/ 4dqpsk信号包络起伏相对较小，比较适合移动通信。此外，它可以采用差分解调，也可以采用相干解调的方式。 - In this thesis , we focused our attention on demodulation and digital signal processing ( dsp ) technique in the dpsk differential detection system used in pico - satellite test and control instructions , mainly from the point of view of software
论文围绕皮卫星通信中测控指令的dpsk差分解调系统，重点从软件角度对通信解调技术和数字信号处理的一系列问题进行了实践和研究。 - The receiver unit mainly consisted of the digital down converter , matched filter , integration and dump module , power detector , symbol tracking processor , differential demodulator , parallel - to - serial conversion module , output processor and afc module
接收部分主要有数字下变频、数字匹配滤波器、积分清洗、功率检测、符号跟踪处理、差分解调、并串处理、自动频率跟踪处理等模块。 - ( decoding the signal from handsets correctly , which depends on whether the comprehension about the channel decoding protocols concerned is right and whether a pattern for data - storing can be developed . ( the rather high requirement for real time processing
解调采用的是2bit差分解调，解调后根据不同信道的类型采用不同的解码方式，再将解码的结果放入与信令模块共享的双口ram ，以便信令模块取走。
