ds digital signal 中文意思是什麼
ds digital signal
解釋
數字信號-
It was found that they were fit for the lpi applications. on the digital signal processing, we studied the demand on compute ability for fast acquest. we designed a new signal form named ds - fh - th signal which costs less in processing but without any lost on the lpi performance
在信號的數字處理方面,分析了直接序列擴頻雷達在信號捕獲階段對計算能力的要求,在不降低系統lpi性能的基礎上,設計了ds - fh - th雷達信號,降低系統對計算能力的要求。 -
Digital signal level 0 - digital signal level 3 ds0 - ds
零階數字信號和三階數字信號 -

This dissertation proposes to adopt poly - phase filtering channelized receiver to receive the special multi - carrier ds - cdma signal, which is studied by this dissertation, and use digital matched filter to de - spread signal
在此基礎上提出採用多相濾波器組通道化接收機來接收本文研究的多載波擴頻通信信號,並使用數字匹配濾波器進行解擴。 -
In the end, implementation of if digital receiver unit of tdrss user transponder by the method of fpga and dsp cooperation design are completed successfully, which leads to good ds - ss if receiver design for the signal whose carrier frequency is 3mhz, pseudorandom code rate is 3mchips / s, data rate is 10kbps, frequency offset is no more 1khz, and modulation mode is bpsk
最後,完成了該中頻數字接收機設計,並對其進行調試和測試。測試結果表明,該接收機能對載頻為3mhz ,頻偏不大於1khz ,偽隨機碼速率為3mchips / s ,信息碼速率為10kbps , bpsk調制的直接序列擴頻中頻信號進行接收,基本滿足設計要求。
