Multi-user diversity scheme is an alternative approach to more traditional techniques like Time Division Multiple Access (TDMA) to increase the capacity of wireless cellular networks. The main idea behind this approach is that the base station selects a mobile user with the best channel condition by taking advantage of the time varying nature of fading channels, thus maximizing the Signal-to-Noise Ratio (SNR). Traditionally, fading and interference have been viewed as the two major impeding factors in increasing the capacity of wireless cellular networks. The Opportunistic Interference Management (OIM) scheme is an approach that takes advantage of the fading in the channel to reduce the negative effects of interference.
