RS (with SIC) is therefore optimum to achieve the sum DoF of the K-user underloaded MISO BC with imperfect CSIT, in contrast with MU LP that is clearly suboptimum (and so is SC SIC since it achieves a sum DoF of unity8) [28].
Numerical results confirm that the proposed user selection scheme achieves a sum rate close to that of the exhaustive search.
It is shown that when certain conditions are satisfied, the proposed scheme is able to achieve a sum rate similar to that of the minimum mean-square error-based coordinated beamforming that relies on instantaneous CSI.
RS achieves a sum-DoF of 2 in the overloaded regime.
Results show that JD can achieve a sum-rate gain of up to 10% or sum-power gain of 0.8 dB.
Interference alignment (IA) is a recently proposed transmission technique for the K-user interference channel (IFC), which is proven to achieve a sum-rate multiplexing gain of K/2 at the high interference regime.
In vivo skeletal muscle ATP turnover rate has typically been observed over considerably longer periods of time to achieve a summed single measurement (3, 45).
As a result, we can achieve a set of rates such that (sum _{i=1}^{3}{R_{i}} geq frac {1}{2} C_{text {sum}}), and by the definition of normalized sum rate, we achieve (alpha = frac {1}{2}). 2 A cut Ω is a subset of (mathcal {V}) such that S∈Ω,D∉Ω, and (Omega ^{c} = mathcal {V} setminus Omega ). 3 The result for m=1 is trivial since we basically have an interference-free network.
Given the assumption of 1-local view, in order to achieve a normalized sum rate of α, each source should transmit at a rate greater than or equal to α n−τ (in linear deterministic model) for some constant τ.
This is due to the fact that from each source's point of view, it is possible that the other S-D pairs have capacity 0. Therefore, in order to achieve a normalized sum rate of α, it should transmit at a rate of at least α n−τ.
For networks in category (b), a simple TDMA achieves a normalized sum rate of 1/3.
