I divide femto cells into two types in LTE_GUI_show_UEs_and_cells.m file according to following.
% Triangular marker
the_marker = ‘diamond’;
if mod(b_,2)==0 % if even
site_MarkerFaceColor = ‘green’; WIFI
else % if odd
site_MarkerFaceColor = ‘red’; LTE femto cell
now, i want to implement CSMA/CA for the femto cells with green face color to access the channel. Basically i want to study coexistence of LTE and WIFI in unlicensed band. i need help in implementing CSMA/CA on femto cell. Have anyone implement it before? kindly reply if you know any thing of little bit. thank you!
