I am wondering why CVX is reporting error in line 6 of the codes below which I have written to maximize the capacity of a femtocell user in an heterogeneous cellular network.
Shannon’s Capacity is C = B.*log(1+SINR).
The concern is in the expression for the SINR part. The equation for SINR is shown in the diagram. I will appreciate any assitance whatsoever.
variables pf(MD,FAP) pm(MD,FAP)
for u = 1:MD
for v = 1:FAP
Cap_femto_obj = Cap_femto_obj + B_RB.*((entr(1+(times( (pf.*Gd_fu), (sigma2 + pf.*G_co + pm.*G_cross), ‘./’ ))))./entr(2));
objective = Cap_femto_obj
