Opportunistic Detection Under a Fixed-Sample-Size Setting

  title={Opportunistic Detection Under a Fixed-Sample-Size Setting},
  author={Wenyi Zhang and H. Vincent Poor},
  journal={IEEE Transactions on Information Theory},
With a finite number of samples drawn from one of two possible distributions sequentially revealed, an opportunistic detection rule is proposed, which possibly makes an early decision in favor of the alternative hypothesis, while always deferring the decision of the null hypothesis until collecting all the samples. Properties of this opportunistic detection rule are discussed and its key asymptotic behavior in the large sample size limit is established. Specifically, a Chernoff-Stein lemma type… CONTINUE READING
