摘要

本文给出了多输入多输出正交频分复用(MIMO-OFDM)系统在有和无视线(LoS)两种拥挤室内环境下的动态信道容量测量结果。根据IEEE 802.11n草案,实验使用了4个发送天线和4个接收天线以及114个5 GHz的子载波。采用固定的接收机信噪比和固定的发射机功率对MIMO-OFDM信道容量进行了分析。研究发现,行人的存在使两种环境下的固定信噪比容量增加,而固定Tx功率容量减少。研究还发现,两种标准下的行人都增加了通行能力累积分布函数(CDF)的扩散。

Capacity analysis of MIMO-OFDM broadband channels in populated indoor environments
This paper presents the results of dynamic channel capacity measurements for a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system in two populated indoor environments with and without line-of-sight (LoS). The experiment used 4 sending and 4 receiving antennas and 114 sub-carriers at 5 GHz as per draft IEEE 802.11n. MIMO-OFDM channel capacity is analysed both with fixed receiver signal-to-noise ratio (SNR) and fixed transmitter (Tx) power criteria. It is found that fixed SNR capacity increased while fixed Tx power capacity decreased in both environments by the presence of pedestrian. It is also revealed that the spread of the capacity cumulative distribution function (CDF) increased due to the pedestrians in both environments with both criteria.
