单频干扰 meaning in Chinese
single frequency interference
single-frequency interference
Examples
- The ber expressions of different type jamming signal is calculated
推导了各种干扰方式的误码率计算公式及单频干扰的最佳频偏。 - The modem can be used under extremely low snr conditions , which snr is - 23 db or there is an hard single - tone interference . it is of good meaning to make the communication under extremely low snr conditions available
该调制解调器可以在信噪比为- 23db或强单频干扰的恶劣信道条件下的实现低速的数据传输，作为一种应急通信手段，对于可靠保障通信的畅通有重要意义。 - The signal format of gps is analyzed , the principle models and mathematical models are established , the ber performance is analyzed in a channel interfered with wide - bandwidth awgn , narrow - bandwidth awgn , transmitted signal , single - tone signal respectively . based on the results above interference methods are discussed and simulated . then the performance of code acquisition and code trace of a digital gps receiver are discussed . the modem of linkl 1 and link4a are modeled and their ber performances are analyzed and simulated in channel s interfered with awgn , single - tone signal and multi - tone signal respectively
