“…At a rate of 16 Mbit/s, the difference between achievable mutual information and simulated throughput is approximately 4 dB. These findings are similar to the results we obtained when analyzing the performance of WiMAX and High-Speed Downlink Packet Access (HSDPA) in [72]. Figure 10 furthermore shows that, for SNRs lower than 14 dB, the TxD mode outperforms OLSM.…”

In this article, we introduce MATLAB-based link and system level simulation environments for UMTS Long-Term Evolution (LTE). The source codes of both simulators are available under an academic non-commercial use license, allowing researchers full access to standard-compliant simulation environments. Owing to the open source availability, the simulators enable reproducible research in wireless communications and comparison of novel algorithms. In this study, we explain how link and system level simulations are connected and show how the link level simulator serves as a reference to design the system level simulator. We compare the accuracy of the PHY modeling at system level by means of simulations performed both with bit-accurate link level simulations and PHY-model-based system level simulations. We highlight some of the currently most interesting research questions for LTE, and explain by some research examples how our simulators can be applied.

“…We show both the absolute and relative losses for these scenarios. The interested reader will find detailed comparisons of WiMAX and HSDPA in both urban and alpine environments in [43]- [45], [47], and [48]. Additionally, (1 Â 1)-, (2 Â 2)-, and even nonstandard (4 Â 4)-element MIMO-aided HSDPA transmission results can also be found in [43]- [45] and [48].…”

“…Several practical scenarios have been characterized by our measurements over the few past years, ranging between two extremes: alpine (Carinthian Alps) as well as urban (downtown Vienna, Austria). Further detailed comparisons may be found in [43]- [45], [47], and [48].…”

In this paper, we propose new Discrete Fourier Transform (DFT)-based beamspace selection algorithms for Massive Multiple Input, Multiple Output (MIMO) receiver operating in realistic multi-user (MU) scenarios. In practical uplink scenarios, there is a power ratio between signals received from different users that complicates performance analysis in MU cases. Our algorithms are inspired by a proportional fair approach to allocating spatial resources for target users. Thus, we analyze performance in terms of coverage (for low-power users) and capacity (for high-power users) and consider the implementation complexity to highlight feasible algorithms. Simulations with realistic non-line-of-sight scenarios generated by the QuaDRiGa 2.0 demonstrate our methods outperform other DFT-based alternatives, such as the beamspace selection based on the projection power maximization.INDEX TERMS 5G, multi-user massive MIMO, beamspace selection, angular domain processing.
