In pico-cell architecture, although utilizing a simple base station and a simplified allocation design help to reduce bit cost, frequency channel interference between/among adjacent cells becomes a serious problem. The pico-cell system is supposed to be used mainly for packet-based communication and the carrier to interference power ratio (C/I) degradation leads to poor network performance. To overcome this drawback, we propose a novel channel allocation algorithm, i.e., a centralized approach that works based on interference information reported by each subscriber station (SS). Both computer simulations and experiments based on implementation clarify that our proposed algorithm is effective
