Weighted Adaptive Lifting-Based Wavelet Transform for Image Coding
In this paper, a new weighted adaptive lifting (WAL)-based wavelet transform is presented. The proposed WAL approach is designed to solve the problems existing in the previous adap...

Nonlinear Turbo Codes for Higher-Order Modulations
— In 1982 Ungerboeck presented a set-partitioning design technique for trellis coded modulation (TCM). Although this technique directly assigns constellation points to the branch...

Iteratively Detected Sphere Packing Modulated OFDM: An Exit Chart Perspective
- A novel iteratively detected Sphere Packing (SP) modulation aided Orthogonal Frequency Division Multiplexing (OFDM) scheme is proposed, which we refer to as the SPOFDM arrangemen...

Three-Stage Serially Concatenated Codes and Iterative Center-Shifting K-Best Sphere Detection for SDM-OFDM: An EXIT Chart Aided
—Iterative K-best sphere detection (SD) and channel decoding is appealing, since it is capable of achieving a nearmaximum-a-posteriori (MAP) performance at a low complexity. Howe...
