Blind Near-MAP Selection Diversity With Multiuser Detection for Multiuser OFDM [PDF]
This letter proposes a receiver algorithm for orthogonal frequency division multiplexing (OFDM) with receiver diversity that uses a new multiuser generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by successive interference cancellation with least-square projection for multiuser detection.

A Low-Complexity Blind Multiuser Receiver for Long-Code CDMA
Receivers for long-code systems are for computational reasons usually based on simple matched-filter techniques, and hence suffer from multiaccess interference.

Semi-blind and group-blind multiuser detection for the MC-CDMA uplink [PDF]
In this contribution both semi-blind and group-blind multiuser detectors designed for uplink MC-CDMA systems are investigated in conjunction with different spreading codes. In the investigated scenario Walsh codes are shown to outperform both Gold codes and Zadoff-Chu codes.

Blind Multiuser Detection for Long-Code CDMA Systems with Transmission-Induced Cyclostationarity
We consider blind channel identification and signal separation in long-code CDMA systems. First, by modeling the received signals as cyclostationary processes with modulation-induced cyclostationarity, long-code CDMA system is characterized using a time ...

Subspace blind adaptive detection for multiuser CDMA [PDF]
Direct adaptive realizations of the linear minimum mean-square error (MMSE) receiver for direct-sequence code-division multiple access possess the attractive feature of not requiring any explicit information of interference parameters such as timing, amplitudes, or spreading sequences; however, they need a training sequence for the desired user ...

Simultaneous Principal-Component Extraction with Application to Adaptive Blind Multiuser Detection
SIPEX-G is a fast-converging, robust, gradient-based PCA algorithm that has been recently proposed by the authors. Its superior performance in synthetic and real data compared with its benchmark counterparts makes it a viable alternative in applications

Dasatinib and quercetin prevent alveolar bone loss in aged mice
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.
