Approaching Waterfilling Capacity of Parallel Channels by Higher Order Modulation and Probabilistic Amplitude Shaping
Parallel, additive white Gaussian noise (AWGN) channels with an average sum power constraint are considered. It is shown how the waterfilling Shannon capacity can be approached by higher order modulation and probabilistic amplitude shaping (PAS). This is achieved by a new distribution matching approach called product distribution matching (PDM). The asymptotic performance of PDM is analyzed by ...
متن کاملGolden Angle Modulation: Geometric- and Probabilistic-shaping
Quadrature amplitude modulation (QAM), deployed in billions of communication devises, exhibits a shaping-loss of πe/6 (≈ 1.53 dB) compared to the Shannon-Hartley theorem. With inspiration gained from special (leaf, flower petal, and seed) packing arrangements (so called spiral phyllotaxis) found among plants, we have designed a shape-versatile, circular symmetric, modulation scheme, the Golden ...
متن کاملOn the Performance of Combined Quadrature Amplitude Modulation and Convolutional Codes for Cross-Coupled Multidimensional Channels
. Abstruct-The performance of cross-coupled, Mary quadrature amplitude modulation (QAM) systems is determined when bandwidth efficient trellis codes are used to combat interference. Performance with and without compensation for cross-coupled interference is presented. It is found that simple trellis codes can maintain the error probability at an acceptable level for cross-coupling parameters...
متن کاملA Mismatched Joint Source-Channel Coding Perspective of Probabilistic Amplitude Shaping: Achievable Rates and Error Exponents
Probabilistic Amplitude Shaping (PAS) is a novel method of reliable commmunication over channels with non-uniform capacity achieving input distribution. The encoder of PAS is a concatenation of a distribution matcher with systematic encoding of a Forward Error Correction (FEC) code whereas the PAS decoder is a concatenation of a mismatched FEC decoder and dematcher. In recent works PAS has been...
متن کاملShaping quality: the use of performance polygons for multidimensional presentation and interpretation of qualitative performance data.
BACKGROUND Measuring outcomes and quality in anaesthesia is challenging. In the UK, there is increased focus on these as a result of changes in Department of Health strategy and the imminent introduction of mandatory revalidation for all doctors. A definition of quality may differ according to the observer's standpoint and numerous performance measures may contribute to overall quality. Patient...
