Journal ArticleDOI
Linear interference cancellation in CDMA based on iterative techniques for linear equation systems
Peng Hui Tan,Lars K. Rasmussen +1 more
TL;DR: The performance of the detectors is studied via computer simulations where it is found that the block approach can provide significantly faster convergence, leading to improved detection delay over the simpler GS iteration, and an increase in the required serial processing speed.
Journal ArticleDOI
Convergence analysis and optimal scheduling for multiple concatenated codes
TL;DR: This correspondence presents an algorithm that finds an optimal decoder schedule which results in convergence and a technique for combining and projecting a series of three-dimensional extrinsic information transfer functions onto a single two-dimensional EXIT chart.
Journal ArticleDOI
The application of semidefinite programming for detection in CDMA
Peng Hui Tan,Lars K. Rasmussen +1 more
TL;DR: A detection strategy based on a semidefinite relaxation of the CDMA maximum-likelihood (ML) problem is investigated and it is demonstrated that this approach provides a good approximation to the ML performance.
Journal ArticleDOI
A matrix-algebraic approach to linear parallel interference cancellation in CDMA
TL;DR: The close relationship between the linear multistage PIC and the steepest descent method (SDM) for minimizing the mean squared error (MSE) is demonstrated and a modified weighted PIC structure that resembles the SDM is suggested which approaches the minimum MSE (MMSE) detector rather than the decorrelator.
Journal ArticleDOI
A matrix-algebraic approach to successive interference cancellation in CDMA
TL;DR: It is shown that linear SIC schemes (single stage and multistage) correspond to linear matrix filtering that can be performed directly on the received chip-matched filtered signal vector without explicitly performing the interference cancellation, leading to an analytical expression for calculating the resulting bit-error rate.
