DATA ALLOCATION WITH MULTI-CELL SC-FDMA FOR MIMO SYSTEMS

Wireless Communication

Joint resource allocation algorithm is used for dynamic user grouping, multi-cell cooperation and resource block allocation for single carrier frequency division multiple access (SC-FDMA) uplink in multi cell virtual MIMO systems. To develop the dynamic multi-cell user grouping criteria using minimum mean square equalization and adaptive modulation with bit error rate constraint. The main advantage of this system is to formulate and solve a new performance maximization problem. Furthermore, to reduce the computational complexity significantly, especially in the case of large numbers of users and RBs, the system present an efficient iterative Hungarian algorithm based on user and resource partitions to solve the problem by decomposing the large scale problem into a series of small scale sub-problems, which can obtain close-to-optimal solution with much lower complexity. The simulation results show that the joint resource allocation algorithm with dynamic multi-cell user grouping scheme achieves better system throughput with BER guarantee than fixed user grouping algorithm.
