符号出错率的一种新表示

A New Representation for the Symbol Error Rate

Adithya Rajan, Cihan Tepedelenlioglu

摘要:

最小距离检测器的符号出错率的任意多维星座受损的加性高斯白噪声的特征在于作为一个产品的完全单调函数与非负功率的信号噪声比。这种表示也适用于损害噪声是复合高斯的情况。利用这个一般性结果,证明了当星座矩阵的秩为1或2时,符号出错率是完全单调的。此外,还得到了任意维星座符号出错率完全单调的充分必要条件。随机排序的无线系统性能的应用程序也进行了讨论。

英文摘要:

The symbol error rate of the minimum distance detector for an arbitrary multi-dimensional constellation impaired by additive white Gaussian noise is characterized as the product of a completely monotone function with a non-negative power of the signal to noise ratio. This representation is also shown to apply to cases when the impairing noise is compound Gaussian. Using this general result, it is proved that the symbol error rate is completely monotone if the rank of its constellation matrix is either one or two. Further, a necessary and sufficient condition for the complete monotonicity of the symbol error rate of a constellation of any dimension is also obtained. Applications to stochastic ordering of wireless system performance are also discussed.
