Cooperative Scheme Using Adjacent Base Stations in Wireless Communication

In a wireless communication system, the failure of base
station can result in a communication disruption in the cell. This paper
proposes a way to deal with the failure of base station in a wireless
communication system based on OFDM. Cooperative communication
of the adjacent base stations can be a solution of the problem. High
performance is obtained by the configuration of transmission signals
which is applied CDD scheme in the cooperative communication.
The Cooperative scheme can be a e ective solution in case of the
particular situation.
