الملخص EN

The goal of the study presented in this paper is to investigate the performance of a new subcarrier allocation strategy for Orthogonal Frequency Division Multiple Access (OFDMA) multicellular networks which employ Multiple Input Multiple Output (MIMO) architecture.

For this reason, a hybrid system-link level simulator has been developed executing independent Monte Carlo (MC) simulations in parallel.

Up to two tiers of cells around the central cell are taken into consideration and increased loading per cell.

The derived results indicate that this strategy can provide up to 12% capacity gain for 16-QAM modulation and two tiers of cells around the central cell in a symmetric 2 × 2 MIMO configuration.

This gain is derived when comparing the proposed strategy to the traditional approach of allocating subcarriers that maximize only the desired user’s signal.
