OFDM-based Waveforms for Joint Sensing and Communications Robust to Frequency Selective IQ Imbalance
Oliver Lang, Christian Hofbauer, Moritz Tockner +3
Orthogonal frequency-division multiplexing (OFDM) is a promising waveform candidate for future joint sensing and communication systems. It is well known that the OFDM waveform is v…
Analysis and Compensation of Carrier Frequency Offset Impairments in Unique Word OFDM
Christian Hofbauer, Werner Haselmayr, Hans-Peter Bernhard +1
Unique Word-orthogonal frequency division multiplexing (UW-OFDM) is known to provide various performance benefits over conventional cyclic prefix (CP) based OFDM. Most important, U…
Doppler-Division Multiplexing for MIMO OFDM Joint Sensing and Communications
Oliver Lang, Christian Hofbauer, Reinhard Feger +1
A promising waveform candidate for future joint sensing and communication systems is orthogonal frequencydivision multiplexing (OFDM). For such systems, supporting multiple transmi…
On the Inclusion and Utilization of Pilot Tones in Unique Word OFDM
Christian Hofbauer, Werner Haselmayr, Hans-Peter Bernhard +1
Unique word-orthogonal frequency division multiplexing (UW-OFDM) is known to provide various performance benefits over conventional OFDM using cyclic prefixes (CP). Most important,…
On the Log-Likelihood Ratio Evaluation of CWCU Linear and Widely Linear MMSE Data Estimators
Oliver Lang, Mario Huemer, Christian Hofbauer
In soft decoding of data bits, the log-likelihood ratios are evaluated from the estimated data symbols. For proper constellation diagrams such as QPSK or 16-QAM, these data symbols…
Non-Systematic Complex Number RS Coded OFDM by Unique Word Prefix
Mario Huemer, Christian Hofbauer, Johannes B. Huber
In this paper we expand our recently introduced concept of UW-OFDM (unique word orthogonal frequency division multiplexing). In UW-OFDM the cyclic prefixes (CPs) are replaced by de…
Classical and Bayesian Linear Data Estimators for Unique Word OFDM
Mario Huemer, Alexander Onic, Christian Hofbauer
Unique word - orthogonal frequency division multiplexing (UW-OFDM) is a novel OFDM signaling concept, where the guard interval is built of a deterministic sequence - the so-called…
Coded OFDM by Unique Word Prefix
Mario Huemer, Christian Hofbauer, Johannes B. Huber
In this paper we propose a novel transmit signal structure and an adjusted and optimized receiver for OFDM (orthogonal frequency division multiplexing). Instead of the conventional…
