Exploring the Physical Layer Frontiers of Cellular Uplink - The Vienna LTE-A Simulator
Communication systems in practice are subject to many technical/technological
constraints and restrictions. MIMO processing in current wireless
communications, as an example, mostly employs codebook based pre-coding to save
computational complexity at the transmitters and receivers. In such cases,
closed form expressions for capacity or bit-error probability are often
unattainable; effects of realistic signal processing algorithms on the
performance of practical communication systems rather have to be studied in
simulation environments. The Vienna {LTE-A} Uplink Simulator is a 3GPP {LTE-A}
standard compliant link level simulator that is publicly available under an
academic use license, facilitating reproducible evaluations of signal
processing algorithms and transceiver designs in wireless communications. This
paper reviews research results that have been obtained by means of the Vienna
LTE-A Uplink Simulator, highlights the effects of Single Carrier Frequency
Division Multiplexing (as the distinguishing feature to LTE-A downlink),
extends known link adaptation concepts to uplink transmission, shows the
implications of the uplink pilot pattern for gathering Channel State
Information at the receiver and completes with possible future research
directions.Comment: submitted to Eurasip Journal on Wireless Communications and
