Journal ArticleDOI
Interleave division multiple-access
TL;DR: A semi-analytical technique is developed based on the density evolution technique to estimate the bit-error-rate (BER) of the IDMA scheme, which provides a fast and relatively accurate method to predict the performance of theIDMA scheme.
Journal ArticleDOI
The Factor Graph Approach to Model-Based Signal Processing
TL;DR: The message-passing approach to model-based signal processing is developed with a focus on Gaussian message passing in linear state-space models, which includes recursive least squares, linear minimum-mean-squared-error estimation, and Kalman filtering algorithms.
The Factor Graph Approach to Model-Based Signal Processing Factor graphs can model complex systems and help to design effective algorithms for detection and estimation problems.

Journal ArticleDOI
Comparison of orthogonal and non-orthogonal approaches to future wireless cellular systems
Peng Wang,Jun Xiao,Li Ping +2 more
TL;DR: It is demonstrated that non-orthogonal approaches have a spectral-power efficiency advantage over orthogonal ones for delay-sensitive applications in fading environments, and that this theoretical advantage can be realized in practice by exploiting recent progress in transmission and detection techniques.
Journal Article
Orthogonal AMP
Junjie Ma,Li Ping +1 more
TL;DR: In this paper, an orthogonal AMP (OAMP) algorithm based on de-correlated linear estimation (LE) and divergence-free non-linear estimation (NLE) is proposed.
