Polarisation dependent MIMO gains on multiuser downlink OFDMA with a 3GPP LTE air interface in typical urban outdoor scenarios |
Abstract | ||
|---|---|---|
Recent studies on spatial multiplexing gain based on antenna polarisation diversity are mostly based on channel measurements or theoretical propagation models. The advantage of using XPD cross-polarised antennas in cellular MIMO-OFDM systems is that XPD antennas save costs and space achieved by a more compact antenna design. The throughput performance is generally considered to be similar to co-polarised antennas with pre-coding. In this paper we show the achievable gains of using cross-polarised antennas as compared to co-polarised antennas at the base station. These cross-polarised antennas are used for adaptive MIMO transmission for typical outdoor scenarios. Our results are based on real-time multiuser (MU) multi-antenna capacity measurements taken with a MIMO-OFDMA system with parameters close to the current 3G-Long-Term-Evolution (LTE) standard. Downlink transmission is considered in a single-cell outdoor scenario. We demonstrate the significant effect of polarisation on the overall system performance, especially on user sum rates when fairness scheduling in OFDMA is applied. |
