One of the major problems that hit mobile communications seriously is Near-far problem. The SN ratio of the user is calculated by mutual interference in a CDMA system.
The following diagram depicts the communication affected by Near-far problem.
From the diagram above, we can see the user A is far away and user B is close to the receiver. Due to this there is a huge difference between the desired signal power and interfered signal power. For user A, the desired signal power will be more as it is far so the SN ratio will smaller and the signal quality is seriously damaged.
