Molecular biology of learning: modulation of transmitter release.
Science, 1982Until recently, it has been impossible to approach learning with the techniques of cell biology. During the past several years, elementary forms of learning have been analyzed in higher invertebrates. Their nervous systems allow the experimental study of

Performance of optimum transmitter power control in cellular radio systems
, 1992Most cellular radio systems provide for the use of transmitter power control to reduce cochannel interference for a given channel allocation. Efficient interference management aims at achieving acceptable carrier-to-interference ratios in all active ...

Channel estimation for OFDM systems with transmitter diversity in mobile wireless channels
IEEE J. Sel. Areas Commun., 1999Transmitter diversity is an effective technique to improve wireless communication performance. In this paper, we investigate transmitter diversity using space-time coding for orthogonal frequency division multiplexing (OFDM) systems in high-speed ...

Reconstitution of transmitter secretion
Current Opinion in Neurobiology, 1993Molecular mechanisms involved in the various stages of transmitter secretion have been studied by perturbing the composition of secretory cells using pharmacological and biochemical agents. An emerging approach is to reconstitute individual steps or the entire sequence of secretion mechanisms in non-secretory cells by loading the cell with presynaptic ...

Transmitter in der Froschlunge
Pfl�gers Archiv European Journal of Physiology, 1968Versuche am Nerv-Lungenpraparat des Frosches (Rana esculenta) hatten zum Ziel, die Art der neuromuskularen Erregungsubertragung zu identifizieren. 1. In Lungenextrakten konnte Acetylcholin, Adrenalin und 5-Hydroxytryptamin (5-HT, Serotonin) bestimmt werden. 2. Eine nerval (0,2–1 Hz) ausgeloste Kontraktion der glatten Muskulatur ist im

Digital coherent optical systems use advanced digital signal processing and modulation techniques at the transmitter and receiver. Therefore, we begin this chapter by reviewing the fundamentals of digital communications, including principles of modulation, channel modeling, and detection. After that, we analyze the basic building blocks that make up an
