of the ia schemes based on the measured environment of the wireless network selecting an ia scheme from among the ia schemes based on the predicted throughputs and communicating with a user terminal based on the selected ia scheme application_number US 201514748996 A description reference will now be made in detail to exemplary embodiments of the present invention examples of which are illustrated in the accompanying drawings wherein like reference numerals refer to the like elements throughout exemplary embodiments are described below to explain the present invention by referring to the figures fig1 illustrates an example of selecting an interference alignment ia scheme based on a signal to noise ratio snr according to an example embodiment the ia scheme may be for example technology for improving transmission efficiency by controlling interference between overlapping access points aps using an equal frequency in a wireless channel environment the ia scheme may be implemented based on various diversity aspects for example an ia may be a scheme of performing zero forcing by dividing a space into two portions such that a signal received from a transmitting end is aligned in one portion and an interference signal received from another transmitting end is aligned in another portion in the above ia scheme an opportunistic interference alignment oia may be used to acquire an increased multi user diversity according to an increase in a number of user terminals included in a basic service set bss thereby improving a maximum throughput for example an achievable throughput when compared to an iterative ia the oia may derive a higher maximum throughput at a low snr at which an influence of interference is less than an influence of noise in this example the bss.
