Center node: "technical report finger replacement schemes for rake receivers in the soft handover region with multiple bss over i n d fading channels"
  Abstract: AbstractA new ﬁnger replacement technique which is applicable for RA KE receivers in the soft handover(SHO) region has been proposed and studied in [1], [2] under the ideal assumption that the fadingis both independent and identically distributed from path to path. To supplement our previous work,we present a general comprehensive framework for the performance assessment of the proposed ﬁngerreplacement schemes operating over independent and non-identically distributed (i.n.d.) faded paths. Toaccomplish this object, we derive new closed-form expressions for the target key statistics which arecomposed of i.n.d. exponential random variables. With these new expressions, the performance analysisof various wireless communication systems over more practical environments can be possible.Index TermsDiversity channels, joint PDF, order statistics, i.n.d fading channels.
