The Version of Record is available online at: https://doi.org/10.1109/LCOMM.2015.2485216.[Abstract]: The MAP and MMSE estimation of Laplace-distributed symbols transmitted over multiple-input multiple-output channels is studied. This is an important problem in analog joint source channel coding with spiral mappings, where the probability density function of the transmitted symbols approximates a Laplace distribution in the low SNR regime. Simulation results are presented to illustrate the suitability of these estimators in uncoded and coded analog communications.engTodos os dereitos reservados.
