A theoretical approach is presented for estimating the quality of signal reception, in an indoor mobile communication system with high transmission bit-rate. A frequency-selective channel model is used for M-ary PSK modulated signals corrupted by additive white noise and interference under Nagakami-Rice fading conditions. Subsequently, the problem of finding a practical way to determine the level of interference (due to frequency reuse from neighbouring m'crocells and dueto the multipath delay spread) is addressed. Thus, a parameter is proposed as a quality factor for measuring, in real-time, the reliability of the communication link. The proposed method helps decision making for on-line nehvork nzanagement such as dynamic channel allocation and adaptive power control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
