摘要

802的广泛接受。提供无线本地网络的ttn技术以及大多数无线局域网使用的2.4 ghz频段的有限尺寸导致了以拥塞和性能差为特征的射频环境。为了减轻这些影响，人们一直在研究不同的频率规划策略，以便最大限度地增加802.11n节点可用的中心频率数量，同时保持相邻信道干扰的影响。受此方法的启发，本工作通过一组广泛的链路级模拟探索了不同载波间隔方案和每种情况下可实现的最大比特率之间的权衡，同时量化了此类干扰的影响。结果表明，干扰功率与期望信号功率的比率是选择载波间间距的关键因素。

Managing 802.11n Adjacent-Channel Interference via Efficient Carrier Spacing in the 2.4-GHz Band

The wide acceptance of the 802.ttn technology for provision of wireless local networks and the limited size of the 2.4-GHz band used by most of them have led to RF environments characterized by congestion and poor performance. Seeking to mitigate these effects, there has been interest in studying different frequency planning strategies in order to maximize the number of center frequencies available for 802.11n nodes while keeping the effects of adjacent channel interference at check. Inspired by this approach, this work explores via an extensive set of link-level simulations the trade-off between the different carrier spacing schemes and the maximum achievable bit rate in each of these scenarios, while quantifying the impact of such interference. Results point at the ratio of interferer power to desired signal power as a key factor in the choice of inter-carrier spacing.
