Bit-Interleaved Coded Modulation Revisited: A Mismatched Decoding Perspective
Alfonso Martinez, Albert Guillen i Fabregas, Giuseppe Caire +1
We revisit the information-theoretic analysis of bit-interleaved coded modulation (BICM) by modeling the BICM decoder as a mismatched decoder. The mismatched decoding model is well…
Outage Probability of the Gaussian MIMO Free-Space Optical Channel with PPM
Nick Letzepis, Albert Guillen i Fabregas
The free-space optical channel has the potential to facilitate inexpensive, wireless communication with fiber-like bandwidth under short deployment timelines. However, atmospheric…
Power Allocation for Fading Channels with Peak-to-Average Power Constraints
Khoa D. Nguyen, Albert Guillen i Fabregas, Lars K. Rasmussen
Power allocation with peak-to-average power ratio constraints is investigated for transmission over Nakagami-m fading channels with arbitrary input distributions. In the case of de…
Bit-interleaved coded modulation in the wideband regime
Alfonso Martinez, Albert Guillen i Fabregas, Giuseppe Caire +1
The wideband regime of bit-interleaved coded modulation (BICM) in Gaussian channels is studied. The Taylor expansion of the coded modulation capacity for generic signal constellati…
Derivative of BICM Mutual Information
Albert Guillen I Fabregas, Alfonso Martinez
In this letter we determine the derivative of the mutual information corresponding to bit-interleaved coded modulation systems. The derivative follows as a linear combination of mi…
Sphere Lower Bound for Rotated Lattice Constellations in Fading Channels
Albert Guillen i Fabregas, Emanuele Viterbo
We study the error probability performance of rotated lattice constellations in frequency-flat Nakagami- block-fading channels. In particular, we use the sphere lower bound on t…
