چکیده
This report describes the analysis of the link adaptation strategy for non-binary LDPC codes in a multicarrier system over a time-variant frequency-selective channel. The transmitted power is equally distributed over a subset of subchannels that are identified through the waterfilling technique. Then the modulation order is adapted to each subchannel in order to increase the throughput of the system given a certain Quality of Service. Simulation results are presented. Keyword list: link adaptation, Adaptive Coding Modulation, Power loading, bit loading, Multi-level Waterfilling, Equal Power, vertical scheduling

متن کاملDopamine Downregulation of Proximal Tubule AT
Systemic and/or locally produced angiotensin II stimulates salt and water reabsorption in the renal proximal tubule. In vivo, dopamine (DA) may serve as a counterregulatory hormone to angiotensin II’s acute actions on the proximal tubule. We examined whether dopamine modulates AT 1 receptor expression in cultured proximal tubule cells (RPTC) expressing DA 1 receptors. Dopamine decreased basal R...
