Performance of an adaptive successive serial-parallel CDMA cancellation scheme in flat Rayleigh fading channels

open access: yes, 2000
The performance of a successive concatenated cancellation scheme for code-division multiple-access (CDMA) uplink transmission in cellular mobile radio is presented. Both serial and parallel cancellation stages are employed.

Root developmental responses to heterogeneous water and nitrogen supply [PDF]

open access: yes, 2012
Better understanding of the interaction between the soil physical properties determining water and nitrate availability and the root proliferation and gene expression components of nutrient acquisition could contribute to food security, but may have been

A new blind adaptive antenna array for GNSS interference cancellation [PDF]

open access: yes, 2005
This paper introduces a new blind adaptive antenna array as a possible solution to the interference cancellation problem. This new technique is compared to three classical ones over two different sensor radiation patterns.

Shoot yield drives phosphorus use efficiency in Brassica oleracea and correlates with root architecture traits [PDF]

open access: yes, 2009
The environmental and financial costs of using inorganic phosphate fertilizers to maintain crop yield and quality are high. Breeding crops that acquire and use phosphorus (P) more efficiently could reduce these costs.

A Reduced-Complexity Partial-Interference-Cancellation Group Decoder for STBCs

open access: yes
In this paper, we propose a reduced-complexity implementation of partial interference cancellation group decoder with successive interference cancellation (PIC-GD-SIC) by employing the theory of displacement structures.

Unit Root Tests With Markov-Switching [PDF]

open access: yes
Diba and Grossman (1988) and Hamilton and Whiteman (1985) recommended unit root tests for rational bubbles. They argued that if stock prices are not more explosive than dividends, then it can be concluded that rational bubbles are not present.

Different root growth patterns in tomato seedlings grown hydroponically under an electric field [PDF]

open access: yes, 2013
Electric fields can determine changes at morphological and physiological levels in plants. In this study, seedlings of Solanum lycopersicum L., grown hydroponically in a floating system, were exposed to a DC 12.0 V m–1 electric field (EF).
