A downlink soft handover scheme is proposed for cell edge users in 4G-LTE systems. To avoid capacity loss in cell edge areas the proposed handover scheme uses multi-cell MIMO cooperated by multiple base stations. Capacity of the 4G LTE is very high than the 3G LTE and also 4G is more faster because the main beam traverse towards the mobile user .4G LTE Variable step size has low mean square error which almost equal to nullify. In the proposed scheme, different multi-cell MIMO transmissions are adaptively exploited based on the spatial correlation of a downlink channel and path loss of adjacent cells by comparing link level capacity. MIMO is computed by using a method called singular value decomposition. SISO is used in the old LTE systems its capacity is less. Radiation pattern for 4G LTE is very high |
