Abstract :
Multiple-input multiple-output (MIMO) is known as an one of the most attractive candidates for large capacity. However, when signal to noise ratio (SNR) is decreased, the propagation character of MIMO is dropped rapidly. For remaining the propagation character of MIMO and/or increasing a capacity, MIMO repeater systems have been discussed. In MIMO multi repeater system, called distributed MIMO repeater system, to obtain bound of capacity of two-way repeater system, we propose a simple mathematical method and statistical Markov chain Monte Carlo method for optimizing distances and transmit power simultaneously.
