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…
Information Rate Loss due to Radiation Decoherence
Alfonso Martinez
The information rates achievable by using electromagnetic radiation affected by thermal noise and signal decoherence are studied. The standard coherent Gaussian model is compared w…
