Information Rates for Channels with Fading, Side Information and Adaptive Codewords
Gerhard Kramer
Generalized mutual information (GMI) is used to compute achievable rates for fading channels with various types of channel state information at the transmitter (CSIT) and receiver…
Stability of Bernstein's Theorem and Soft Doubling for Vector Gaussian Channels
Mohammad Mahdi Mahvari, Gerhard Kramer
The stability of Bernstein's characterization of Gaussian distributions is extended to vectors by utilizing characteristic functions. Stability is used to develop a soft doubling a…
Experiments on Bipolar Transmission with Direct Detection
Thomas Wiegart, Daniel Plabst, Tobias Prinz +6
Achievable information rates of bipolar 4- and 8-ary constellations are experimentally compared to those of intensity modulation (IM) when using an oversampled direct detection rec…
Low-Resolution Precoding for Multi-Antenna Downlink Channels and OFDM
Andrei Stefan Nedelcu, Fabian Steiner, Gerhard Kramer
Downlink precoding is considered for multi-path multi-input single-output channels where the base station uses orthogonal frequency-division multiplexing and low-resolution signali…
Achievable Rates for Short-Reach Fiber-Optic Channels with Direct Detection
Daniel Plabst, Tobias Prinz, Thomas Wiegart +5
Spectrally efficient communication is studied for short-reach fiber-optic links with chromatic dispersion (CD) and receivers that employ direction-detection and oversampling. Achie…
Regular Perturbation and Achievable Rates of Space-Division Multiplexed Optical Channels
Francisco Javier García-Gómez, Gerhard Kramer
Regular perturbation is applied to space-division multiplexing (SDM) on optical fibers and motivates a correlated rotation-and-additive noise (CRAN) model. For S spatial modes, or…
