An MGF-Based Unified Framework to Determine the Joint Statistics of Partial Sums of Ordered i.n.d. Random Variables

Provided by: Institute of Electrical & Electronic Engineers Topic: Software Format: PDF
The joint statistics of partial sums of ordered Random Variables (RVs) are often needed for the accurate performance characterization of a wide variety of wireless communication systems. A unified analytical framework to determine the joint statistics of partial sums of ordered independent and identically distributed (i.i.d.) random variables was recently presented. However, the identical distribution assumption may not be valid in several real-world applications. With this motivation in mind, the authors consider in this paper, the more general case in which the random variables are independent but not necessarily identically distributed (i.n.d.).
