This correspondence presents a simple method to accurately compute the error probability of bit-interleaved coded modulation (BICM). Thanks to the binary-input output-symmetric (BIOS) nature of theâ€¦ (More)

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 defined forâ€¦ (More)

This paper studies likelihood decoding for channel coding over discrete memoryless channels. It is shown that the likelihood decoder recovers the same random-coding error exponents as theâ€¦ (More)

This paper presents a simple and very accurate method to evaluate the error probability of bit-interleaved coded modulation. Modelling the channel as a binaryinput continuous-output channel with aâ€¦ (More)

We show that Gallager's random coding error exponent of an arbitrary binary-input memoryless symmetric channel is upper-bounded by that of the binary erasure channel and lower-bounded by that of theâ€¦ (More)
