Sum-Rate Capacity for Symmetric Gaussian Multiple Access Channels with Feedback
Erixhen Sula, Michael Gastpar, Gerhard Kramer
The feedback sum-rate capacity is established for the symmetric -user Gaussian multiple-access channel (GMAC). The main contribution is a converse bound that combines the depend…
Optimization of Bit Mapping and Quantized Decoding for Off-the-Shelf Protograph LDPC Codes with Application to IEEE 802.3ca
Fabian Steiner, Gerhard Kramer
Protograph-based, off-the-shelf low-density parity-check (LDPC) codes are optimized for higher-order modulation and quantized sum-product decoders. As an example, for the recently…
Joint State Sensing and Communication: Optimal Tradeoff for a Memoryless Case
Mari Kobayashi, Giuseppe Caire, Gerhard Kramer
A communication setup is considered where a transmitter wishes to simultaneously sense its channel state and convey a message to a receiver. The state is estimated at the transmitt…
Experimental Verification of Rate Flexibility and Probabilistic Shaping by 4D Signaling
Fabian Steiner, Francesco Da Ros, Metodi Plamenov Yankov +4
The rate flexibility and probabilistic shaping gain of -dimensional signaling is experimentally tested for short-reach, unrepeated transmission. A rate granularity of 0.5 bits/Q…
Analysis of Massive MIMO and Base Station Cooperation in an Indoor Scenario
Stefan Dierks, Gerhard Kramer, Berthold Panzner +1
The performance of centralized and distributed massive MIMO deployments are analyzed for indoor office scenarios. The distributed deployments use one of the following precoding met…
