- Abstract
- Nowadays, a huge number of WiFi devices are distributed in anywhere place. Because tremendous WLAN devices are transmitting in ISM bands, the interference problem has emerged as an important issue. The simple method to solve the interference problem is to avoid to the other vacant operating channel. However, current ISM band might be already shortage because of operating many WiFi devices. So, the researches about interference management like interference alignment (IA) which multiple nodes can simultaneously transmit in the same frequency band without interfering each other have received much attention. Most of the IA algorithms have researched to just obtain the precoding and decoding vector. To operate the IA algorithms in the real system such as 802.11 WiFi network or LTE cellular network, however, the operational procedure to function IA transceiver design is also needed. So, we propose a novel IA functional sequence protocol with our IA developed algorithm and evaluate the throughput considering protocol overhead. © 2014 IEEE.
