title = "Optimization of coded modulation with mapping by superposition using EXIT charts",
abstract = "We consider signal constellations and bit-to-symbol mappings that arise from the superposition of signals from several layers. This mapping by superposition is applicable to both multi-level coding (MLC) and bit-interleaved coded modulation (BICM). By adjusting the power allocation to the layers, we are able to design a large variety of signal constellations. For some power allocations, the transmitted signal is approximately Gaussian, as required to approach the AWGN capacity. An iterative receiver with a low complexity soft interference canceler is investigated. To analyze the iterative system and optimize the power allocation to the layers, we derive analytic EXIT functions of the interference canceler for the MLC and BICM schemes. To predict the error rate performance at high signal-to-noise ratio (SNR), we provide analytical error bounds.",
