To support spatial scalability, the scalable extension of H.264/AVC (SVC) uses video cropping or uniform scaling to downscale the original higher-resolution (HR) sequence to a lower resolution (LR) one. Both operations, however, will cause critical visual information loss in the retargeted frames. The content-adaptive spatial scalability SVC coders (CASS-SVC) use non-homogeneous scaling to avoid critical...
Lattice reduction aided decoding has been successfully used for signal detection in multiinput and multioutput (MIMO) systems and many other wireless communication applications. In this paper, we propose a novel enhanced Jacobi (short as EJacobi) method for lattice basis reduction. To assess the performance of the new EJacobi method, we compared it with the LLL algorithm, a widely used algorithm in...
In this paper, we apply q-ary LDPC codes to differential modulation systems, and study the design and performance of the resultant coded modulation systems. A low-complexity joint detection/decoding method for noncoherent demodulation is proposed, in which the hard-message-passing strategy is used for a joint factor graph. It combines trellis-based differential detection aided with channel prediction...
The under-determined problem in Higher Order Ambisonics (HOA) makes it hard for larger accurate reproduction area especially at high frequencies. In this paper, the least absolute shrinkage and selection operator (LASSO) algorithm is used to solve the problem by obtaining the sparse representation of the original plane wave field. The algorithm minimizes the squared error between the original and...
