Catecholamines such as norepinephrine, epinephrine, and dopamine are closely related to the autonomic nervous system, suggesting that panic disorder may involve elevated catecholamine levels. This study investigated basal and posttreatment catecholamine levels in patients with panic disorder. A total of 29 patients with panic disorder and 23 healthy controls participated in the study. Panic disorder...
We consider an error pattern estimation scheme which provides lower complexity and improved error performance for iterative receiver. While conventional iterative receiver only considers fixed number of iterations, proposed scheme operates iterations adaptively by removing unnecessary iterations and applying an error correction scheme. Based on simulation results, proposed scheme reduces both computational...
Iterative signal detection based on energy spreading transform (EST) in multiple input multiple output systems has been shown to perform close to the genie bound with the complexity of linear receivers. In this paper, we consider a transmit antenna selection scheme for the EST based iterative receiver and propose some transmit selection criteria. Simulation results are provided to verify the usefulness...
