On the Pilot Carrier Placement in Multicarrier-Based Systems [PDF]
IEEE Transactions on Signal Processing, 2014 In traditional multicarrier systems, the pilot carriers used to estimate the channel are placed as uniform as possible over the bandwidth. However, with the raise of cognitive radio systems, where the multicarrier system is used by the secondary users, parts of the bandwidth are not available for transmission as primary users are active in these bands.

Carrier-Based Drug Delivery System for Treatment of Acne [PDF]
The Scientific World Journal, 2014 Approximately 95% of the population suffers at some point in their lifetime from acne vulgaris. Acne is a multifactorial disease of the pilosebaceous unit. This inflammatory skin disorder is most common in adolescents but also affects neonates, prepubescent children, and adults.

Optimal training sequences for channel estimation in cyclic-prefix-based single-carrier systems with transmit diversity [PDF]
, 2004 In this paper, we investigate a new class of training sequences that are optimal for least squares (LS) channel estimation in systems employing transmit diversity and single-carrier (SC) modulation with a cyclic prefix (CP) extension.

The Dual Carrier ABSK System Based on a FIR Bandpass Filter [PDF]
Sensors, 2014 The special impacting filter (SIF) with IIR structure has been used to demodulate ABSK signals. The key points of SIF, including the resonance circuit’s high Q value and the “slope-phase discrimination” character of the filter sideband, are demonstrated in the paper.
