Analysis is made of non-directional channels by using site-based iterative modeling

thus obtaining the specific iterative formula.For rooms with furniture

the optical gain formula of LOS is presented.Impulse responses when reflection times k=0

1

2 are simulated by MATLAB programming and the simulation graphics given and explained.In addition

the impulse responses for rooms without furniture in the same conditions are also simulated and compared with those for rooms with furniture

leading to the conclusion that the non-LOS components increase along with the height of the rooms.
