摘要
MIMO-OFDM把OFDM技术和MIMO技术的优势结合起来,在不需要增加传输功率和扩大带宽的前提下能够增加数据的传输速率,正在成为无线通信的一个研究热点。简单介绍了MIMO-OFDM技术的原理以及实现MIMO-OFDM的关键技术,同时讨论了其在下一代高速无线局域网标准802.11n中的应用。
Combining the advantages of OFDM and MIMO technologies, MIMO-OFDM can significantly increases the data throughput without increasing the transmission power and enlarging the bandwidth, and is becoming a research hotspot in the wireless communications. This paper briefly introduces the basic theories and key technologies of MIMO-OFDM and discusses the application in the next-generation high throughput WLAN standard--IEEE 802.11n.
