BER=L erfc . Title: Bit Error Rate vs. Q-factor Author: California Scientific, Inc. Subject

2022年12月2日 · 性能评估的关键指标包括误码率(BER)和质量因子(Q-factor)，这两个参数对于保证通信质量至关重要。 相比于传统的互补检测技术，SPD显示出显著的优势：它能实现最低 …

2022年5月14日 · 数字接收机的性能指标由比特误码率（ber）决定，定义ber为码元在传输过程中出现差错的概率，工程中常用一段时间内出现误码的码元数与传输的总码元数之比来表示。

BER = [BER err/(size*iter)]; end semilogy(SNR,BER);grid;xlabel(’E_bN_0’);ylabel(’BER’); title(’BPSK over AWGN channel’); The following program uses some advanced functions of …

误码率(ber) BER 是衡量传输质量的终极值。 耦合到光纤的光信号受噪声、非线性、色散(PMD/CD)等因素的影响造成波形失真，到达光纤链路末端时接收机把光信号重新转换成电信 …

由于snr与osnr关联，snr与ber有关联，ber与q关联，evm与snr关联，从而可以得出的结论是ber、q、evm、snr、osnr之间都是存在确定关系的，理论上只要知道其中任何一个，都可以换算得 …

Q is sometimes referred to as the “signal-to-noise ratio in voltage (or current) units” In my view this is not a useful definition: Q is Q •If the noise is known to be Gaussian, Q fully determines …

The Q function is used (in my little experience) as a convenient way to compute the BER without explicitly showing the error or complementary error function (erf and erfc). Now a few basic …

Usually the Q factor is platter versus an increasing range of launched power (LP). therefore, for smaller LP you should get higher BER and very low BER or equal to 0 when LP is high. If your...

As the Q factor specifies the BER completely, one can realize a BER below 10-9 by ensuring that Q exceeds 6. The value of Q should exceed 7 if the BER needs to be below 10-12. Several …
