Under the circumstance of dynamic running with changing transmission channels, the bit error rate is 10 -12 , the best sensitivity of receivers is up to -32dBm, and the largest power cost is only 0.5dB.
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。
The error-proneness (the bit error rate as high as 10e-3, even 10e-2) and the large delays (the round trip time as high as 100-200ms) of wireless links make headercompression as defined in CRTP (Compressed RTP) perform less than well.
In digit modulation,signal transmission quality mainly hinges on Bit Error Rate(BER), so that, on thesame ratio value of the signal energy per bit and noise power spectrum density, thelower BER modulating method is , the lesser the satellite power is required;
Based on analysis of the distribution of error patterns in mobile channel,an adaptive error controlling is proposed. This scheme can adaptively select one of the three different error correcting codes which fits to the variation of the bit error rate of the channel to achieve high throughput.
This paper analyzes and studies the performance of SFH/MFSK communication systems over short-wave Rayleigh and Rician fading channels with multipath time delay,and develops the exact expression of bit error rate (BER), shows the effects of the numberand strength of multipath inteference on system performance, and their numerical results andperformance curves are given.
The upper bound Qc ≈ 11% on the bit error rate compatible with secure key distribution is determined by solving the transcendental equation
When no counts are detected in the control time slot, the protocol guarantees secure key distribution if the bit error rate in the sifted key does not exceed 50%.
The effect of birefringent disorder on the bit error rate (BER) in an optical fiber telecommunication system subject to amplifier noise may lead to extreme outages, related to anomalously large BER values.
For the quantum channel, the bit error rate will be 0.035 by using 7.0-dB intensity difference squeezing compared with our previous result of 0.067 by using 4.9-dB intensity difference squeezing.
Testing results of the BER (Bit Error Rate) tell us that the new adaptive equalizer for nonlinear channels is superior to the conventional linear equalizers in the equalization performances.
