The average SNR for the first four users are and for the second user.
Figure 9 Optimal time-sharing coefficients versus (a) transmission power T and (b) the second user fading coefficient μ 2. N = 2 users, short-term power constraint, equal-probability fading quantization.
However, first user causes strong interference on the second receive antenna of the second user, and the second users disturb significantly the signal received by the first user in his first antenna.
There is likely more idle time and unused resources if the second user is accommodated but the overall profit will be higher (0.5-0.1=$0.4/hour).
The first frontier line, (where denotes the covariance for which ) is obtained when holding the total transmit power for the first user fixed and varying the total transmit power for the second user from zero to.
A schedule, which is a sequence of power and rate allocations, is feasible if it sends B(1)(W) < ∞ bits to the first user and B(2)(W) < ∞ to the second user (with a certain level of reliabilitya), without violating causality (at any time, using available energy and data by that time).
The BER performance of two streams of the first user and the third user are shown.
I'm trying out the sparser and more confusing interface right now and the first user I hit was masturbating.
Therefore, ( {overline{mathbf{F}}}^k ) and R k are designed step-by-step, which starts by computing the transmit space matrix and the receive processing matrix of the first user, then computes the matrices for the second user by utilizing the receive processing matrix of the first user and so on.
Note that if the decoding order is (2, 1), the receiver first decodes the second user's signal in the presence of interference from first user's signal, and subsequently decodes the first user's signal with no interference.
