Summary: 
In a wireless communication system, the base station failure can result in a communication disruption in the cell. This letter aims to propose an alternative way to cope with the base station failure in a wireless communication system, based on MIMO-OFDM. Cooperative communication can be a solution to the problem. Unlike general cooperative communication, this letter attempts to cover cooperation among adjacent base stations. This letter proposes a specific configuration of transmission signals which is applied to the CDD scheme. The proposed cooperative system can obtain multiplexing gain and diversity gain at the same time. A more reliable performance can be obtained by the proposed cooperative system which uses cooperation of adjacent base stations.
