RECONFIGURABLE ANTENNAS FOR PERFORMANCE ENHANCEMENT OF INTERFERENCE NETWORKS EMPLOYING INTERFERENCE ALIGNMENT |
摘要 |
By using reconfigurable antenna based pattern diversity, an optimal channel can be realized in order to maximize the distance between two subspaces, thereby increasing sum-rate. The inventors show the benefits of pattern reconfigurability using real-world channels, measured in a MIMO-OFDM interference network. The results are quantified with two different reconfigurable antenna architectures. An additional 47% gain in choral distance and 45% gain in sum capacity were achieved by exploiting pattern diversity with IA. Due to optimal channel selection, the performance of IA can also be improved in a low SNR regime. |
