摘要
In this paper, a new approach has been introduced for the bit, sub-carrier and power allocation problem in multi-user Multiple-Input Multiple-Output(MIMO) Orthogonal Frequency Division Multiplexing(OFDM) systems. Resource allocation problem which is non-linear due to the Co-Channel-Interference(CCI) has been transformed into a linear form and has been solved with the aid of the Branch-and-Bound method which is one of the effective integer programming methods that yields optimum results. For the present resource allocation problem, it has been demonstrated that the performance of MIMO systems are superior to that of single antenna systems.
