BER performance comparison for single-user MIMO technology in different wireless scenarios |
| |
Abstract: | In the background of LTE-Advanced, based on the single-user MIMO spatial multiplexing technology and space diversity of IMT-Advanced channel model, simulation analysis is done to the bit error rate performance in-depth in different wireless scenarios and different modulation modes. And combining with wireless communication features of the scene,we can get the conclusion: spatial multiplexing /spatial diversity technology performance is not the same in different wireless scenarios. The conclusion has a certain reference value about the actual design for LTE-Advanced system. |
