Communication systems in practice are subject to many technical/technological constraints and restrictions. Multiple\ninput, multiple output (MIMO) processing in current wireless communications, as an example, mostly employs\ncodebook-based pre-coding to save computational complexity at the transmitters and receivers. In such cases,\nclosed form expressions for capacity or bit-error probability are often unattainable; effects of realistic signal processing\nalgorithms on the performance of practical communication systems rather have to be studied in simulation\nenvironments. The Vienna LTE-A Uplink Simulator is a 3GPP LTE-A standard compliant MATLAB-based link level\nsimulator that is publicly available under an academic use license, facilitating reproducible evaluations of signal\nprocessing algorithms and transceiver designs in wireless communications. This paper reviews research results that\nhave been obtained by means of the Vienna LTE-A Uplink Simulator, highlights the effects of single-carrier\nfrequency-division multiplexing (as the distinguishing feature to LTE-A downlink), extends known link adaptation\nconcepts to uplink transmission, shows the implications of the uplink pilot pattern for gathering channel state\ninformation at the receiver and completes with possible future research directions.
