Harmonious Wireless Networks: From the Perspective of Interference Management
In wireless networks, the desired signal of a specific user is typically an undesired interfering signal for untended receivers. However, from the perspective of an entire wireless network, the coexistence of useful signals and interfering signals is unavoidable and often is beneficial in throughput terms. The useful signals and interfering signals are complementary. They are in juxtaposition to each other in the context of a single communication link, while they are in symbiosis within the framework of the networks, which can be described by Chinese traditional culture symbol of “Yin” and “Yang”. A wireless network having optimal performance must be a harmonious network, where the interfering and useful signals harmoniously coexist in an optimal balance. Interference management plays the critical role in arriving at this optimal balance.
