Efficient Scheduling and Interference Alignment for Hyper MIMO - OFDM in Real Time WI-Max Systems

Hyper (or large scale) multiple-input multiple output (MIMO) is one of the key technologies in next generation multi-user cellular systems. This wireless communication systems can attain higher throughput through interfering alignment. For a small numeral of users, determining the greatest possible degree of independence as well as the possibility of interfering alignment in MIMO system is well studied. However, the issue of preparation in system employing interfering alignment and serving a large amount of users has acknowledged little attention so far. A stochastic association optimization trouble and suggest a development and intervention alignment (SIA) algorithm. In each event slot, SIA schedule some users among various opposing ones to broadcast data, and determine programming and decode matrix for the selected users. Packet admittance control is performing in each time slot. A heuristic semi dispersed algorithm (SDSIA), which has a lower computational difficulty than the SIA algorithm. To contrast the performance of SDSIA with other approach which do not at the same time exploit interference alignment and scheduling and find that the combination of these two technique increase the attainable data rate radically.
