摘　　要：数字通信系统的误码率是评价数据通过系统传输后完整性的一个重要的、有价值的数值。结合统计知识通过有限时长的测试得到发生一个比特误码的概率估计。在此基础上分析发现估计的质量随测试时间的延长而提高,他可用统计学中的置信度方法来量化,从而回答了“需要传送多少比特才能证明系统的误码率”问题。The error code rate of the numeral communication system is an important and valuable character after the data delivers through a system. Combined with the knowledge of possibility we estimated it. With the help of the possibility analysis the more correct the error code rate is estlmated,the longest the test is taken. Based on the definition of the error code rate,the paper provides the zone estimate of the error code rate, then gives＂ how many bits must be deliver to prove the mistaken code rate of the system＂.

关 键 词：数字通信 置信区间 误码率 统计学
