Achievability of the Rate ${1/2}\log(1+\es)$ in the Discrete-Time Poisson Channel
Alfonso Martinez
A simple lower bound to the capacity of the discrete-time Poisson channel with average energy $\es$ is derived. The rate ${1/2}\log(1+\es)$ is shown to be the generalized mutual in…
Low-Signal-Energy Asymptotics of Capacity and Mutual Information for the Discrete-Time Poisson Channel
Alfonso Martinez
The first terms of the low-signal-energy asymptotics for the mutual information in the discrete-time Poisson channel are derived and compared to an asymptotic expression of the cap…
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…
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…
