bound on error

基本解释

An upper bound on the bit error rate is derived. The comparison of the performance of the above receiver with that of optical PPM-CDMA system without optical hard-limiter is given.
在系统中存在多用户干扰及接收机散粒噪声的情况下，推导出该系统误码率上限，并对该系统特性与无光硬件限幅器的光PPM-CDMA通信系统特性作了比较。
The performance of the system is evaluated when considering the effects of both multi user interference and photo detector shot noise. An upper bound on the bit error rate is derived.
在系统中存在多用户干扰及接收机散粒噪声的情况下，推导出该系统误码率上限，并对该系统特性与无光硬件限幅器的光PPM- CDMA通信系统特性作了比较。
As a lower bound on mean square error of parameter estimate, the Cramér-Rao lower bound(CRLB) is generally used to decide to what degree a suboptimal estimate method is close to its optimal fashion.
克拉美-罗下限（CRLB）作为参数估计所能达到的最低误差限，常被用来衡量算法估计性能的优劣程度。
