INTERCELL INTERFERENCE MITIGATION IN MICROCELL USING DYNAMIC CELL SELECTION TECHNIQUE

In large cellular network macro cells are used as they cover large areas about more than 5km in radius but they have drawbacks when we consider the services between these cells, the areas where the signal quality decays are large shopping malls, small garages, tunnels and underground railways, as macro cells  is unable to cover these specific areas. So here the microcells are required. Microcells cover almost 1Km radius so the areas where the macro cells are unable to provide services, microcells are used. Microcells are deployed relatively closer than macro cells so they experience intercell interference, which occurs when UE(user equipment) is at edge of a cell and receiving signals from two base stations simultaneously but with same carrier frequency, here problem arises for the user for the selection of base station, so DCS (Dynamic cell selection) is applied between the cells to reduce the interference between the cells.
