However, because of various noise source and inter symbol interference (ISI), one 2 bit reversing error event (2 BREE) between the two digits of a 1 and a 0 is easy to occur in a detected codeword compared with an original modulation codeword, which causes about a 3 bit error on the average in a 6 bit dataword for the 6∶8 natural binary order mapping constant weight modulation code (NCWMC).
The systematic structure and the anti-jamming method of JTIDS is analyzed, the bit error rate of JTIDS is studied and modulated in the Gaussian noise and partial band jamming, and the result of modulation is analyzed.
During the BPSE process, a high-speed special mode frame is sent, bit error rate (BER) is fed back to the sender, as well as signal to noise (SNR) and BERs for each rate are obtained by looking up the empirical BER/SNR curve.
其中，BPSE先通过发送高速特征序列串来测量比特误码率(Bit ErrorRate)，然后根据BER／SNR(Signal to Noise Ratio)经验曲线，查表得出当前信道的SNR以及当前SNR下各个速率的BER。
Bipolar voilations(BPV),framing errored bits,and coded-detected errors are commonly used to estimate the bit error ratios(BER)and the respective numbers of errored seconds (ES)and severely errored seconds(SES)that are fundamental parameters in characterizing the performance of digital transmission systems.
在不中断业务误码测量中,双极性违例(BPV)、帧比特错误、编码错误,通常被用来估计比特误码率、误码秒 ES、以及严重误码率秒 SES 等基本的误码性能参数。
The bit error performance is correlative not only with the interference-signal ratio (ISR), the frequency offset and the phase of the CW interference sensitively, but also with the individual spread spectrum code sequence.
The throughput of LANs with the DCF mechanism under high load and in noise is evaluated by an analytical method, which ensures high estimation accuracy for any values of protocol parameters and bit error rates.
For a given distance-d weight density, the decoding bit error probability depends on an encoder property, viz., the number of taps in the tap-minimal encoder pseudoinverse.
Among all convolutional encoders that encode a given tailbiting code, the systematic one has the tap-minimal encoder pseudoinverse with fewest taps and, hence, gives the smallest bit error probability.
The upper bound Qc ≈ 11% on the bit error rate compatible with secure key distribution is determined by solving the transcendental equation
