Cognitive power adjustment for OFDM-based wireless communication system: an empirical study

In this paper, we describe an empirical study on the impact of throughput performance when transmission power is adjusted. This experiment was conducted in an office environment for an OFDM-based wireless communication system such as WiFi 802.11g protocol network . We present a power selectio...
