SCMA codebook design based on resource block constellation
Published 2018-09-01“…Aiming at the problems of typical sparse code multiple access codebook design scheme based on multidimensional mother constellation that the complexity is high and the minimum Euclidean distance between constellation points on resource blocks is difficult to determine,a SCMA codebook design scheme based on resource block constellation was proposed.By converting the design of multidimensional mother constellation into the design of two-dimensional resource block constellation,the design complexity of constellation was reduced.And the codebook design scheme starting from resource block constellation could maximize the minimum Euclidean distance between constellation points on resource blocks,which was better than the design method in which user codebooks were obtained from multi-dimensional mother constellation.Simulation results show that the proposed SCMA codebook design scheme based on resource block constellation can significantly improve the BER performance of system compared with the typical codebook design scheme based on multidimensional mother constellation.…”

Noncoherent unitary space-time design base on Grassmann manifold
Published 2013-10-01“…A novel search technique was presented for designing noncoherent unitary space-time constellation.First of all,a unitary matrix framework based on Grassmann manifold was defined.Under the constraint of this framework,a dis-tance threshold was set by using the existing minimum Frobenius norm of optimal packing distribution on the Grassmann manifold,and the points were searched for whose minimum chordal Frobenius norm exceeds the threshold by changing the amplitude and phase of every entry in the unitary matrix.At last,the whole unitary space-time constellation with minimum chordal Frobenius norm maximum was gotten.Numerical simulations indicate that this new constellation perfor better than the present codes.…”

Syn‐Aug: An Effective and General Synchronous Data Augmentation Framework for 3D Object Detection
Published 2025-06-01“…ABSTRACT Data augmentation plays an important role in boosting the performance of 3D models, while very few studies handle the 3D point cloud data with this technique. Global augmentation and cut‐paste are commonly used augmentation techniques for point clouds, where global augmentation is applied to the entire point cloud of the scene, and cut‐paste samples objects from other frames into the current frame. …”

Simple constellation shaping for BICM-ID
Published 2015-06-01“…A novel method of constellation mapping is presented for bit-interleaved coded modulation (BICM) by combining geometry shaping with probabilistic shaping.The transmitted signal points of a practical signal constellation approach the optimal input distribution by exploiting a many-to-one mapping with some signal points unused.With this method,shaping gain can be achieved conveniently with the help of iterative decoding between demodulation and decoder.The optimizations of signal constellation and the mapping from symbols to signal points are performed by the analysis of capacity and the extrinsic information transfer chart.Simulation results show that the proposed constellation mapping outperforms the traditional Gray mapping for BICM with iterative decoding in both AWGN and Rayleigh channels.And the shaping gain achieved can be improved with the increase of the constellation size.…”
