Blind adaptive noncoherent multiuser detection for nonlinear modulation
Noncoherent multiuser detection for nonlinear modulation was recently studied and the idea of phase-independent noncoherent decorrelation was introduced and three post-decorrelative detectors were obtained and analyzed. However, their implementation requires the knowledge of the signature waveforms of all the users, which may be available only for centralized implementation. In this paper, we o...
متن کاملNoncoherent MMSE Multiuser Receivers for Nonorthogonal Multipulse Modulation and Blind Adaptive Algorithms
Noncoherent minimum mean-squared error (MMSE)-based multiuser receivers are proposed for nonorthogonal multipulse modulation. The three proposed receivers have a common MMSE pre-filter and are followed by one of three distinct noncoherent decision rules. The simplest decision rule selects the maximum magnitude of the MMSE filter outputs and the other two decision rules account for the second-or...
متن کاملBlind adaptive multiuser detection
The decorrelating detector and the linear minimum mean-square error (MMSE) detector are known to be effective strategies to counter the presence of multiuser interference in code-division multiple-access channels; in particular, those multiuser detectors provide optimum near-far resistance. When training data sequences are available, the MMSE multiuser detector can be implemented adaptively wit...
متن کاملNoncoherent Decision Feedback Multiuser Detection for Nonorthogonal Multipulse Modulation
| The problem of noncoherent multiuser detection for nonorthogonal multipulse modulation (NMM) over the Gaussian multiuser channel was studied in [1]. In that work, the idea of noncoherent decorrelation for NMM was introduced and post-decorrelative detectors were derived and analyzed. In this paper, we introduce the concept of noncoherent decision feedback that forms the basis for another set o...

These receivers have a common MMSE prefilter and are followed by one of three phase-independent decision rules.
