High speed bert which has been used in bit error rate test in the synthe - sizing and processing terminal system of the earth station has acquired a good effect 高速误码率测试仪已经用于地面站综合处理终端系统的误码检测中,并已取得良好效果。
Their system constructures and bit error rates are analysised we can point out that 2 - d and 3 - d ocdma system will become an important developing direction 指出多维ocdma系统是今后的一个重要发展方向。第三章首先对双极性序列的性质进行讨论和研究。
The system can transmit data one - way over a distance of up to 1 kilometer at a bit - rate of 10 kbps in shallow water , and the bit error rate was less than 5 percents 系统能够在浅海环境下,远到1km的距离上以10kbps的数据率单向传输数据,其误比特率小于5 。
Just like the theoretical analyses , results demonstrate that the two codes can correct nine errors and eighteen errors respectively . the bit error rates have been improved correspondingly 结果表明纠错能力符合理论要求,分别可以达到纠9个和18个错误,并且误码率也得到改善。
The simulation results also tell us the bit error rate ( ber ) of lll detection deceased much faster than the other two detection algorithms with the increasment of signal to noise ratio ( snr ) 随着信噪比的增加,格约简辅助检测算法的误码率曲线下降速度明显增快,且优于其它两种算法。
