Abstract: A receiver for a direct sequence spread spectrum signal subject to interference from a locally transmitted or received frequency-hopped spread spectrum signal includes a programmable notch filter which is controlled in accordance with the code sequence of a frequency-hopped signal to reject frequencies corresponding to those producing interference

Abstract: A multi-pressure reheat combined cycle configuration in which the HP steam turbine exhaust temperature is colder than the HP steam saturation temperature and the coldest section of the reheater is placed downstream of the high pressure evaporation section in the heat recovery steam generator gas path with respect to the direction of exhaust gas flow. When configured in this manner, the optimum reheat pressure for the cycle is lower then for a cycle with all reheating taking place upstream of the HP evaporation section in the HRSG gas path, and the cycle output and efficiency are improved.
