The symbols have a discrete number of possible values. The unit further includes a receiver adapted to receive a data burst of the transmitted signals, memory with the predetermined pilot symbols and a plurality of signals filters (interpolators), a comparator, a processor, and an output. The comparator compares the pilot symbols in a received data burst with the predetermined pilot symbols in the memory to determine correction factors for the pilot symbols. The processor uses the pilot symbol correction factors and the plurality of signal filters to derive a set of data symbol correction factors for each of the signal filters. The processor also adjusts discrete possible values of the data symbols by the data symbol correction factors and compares those adjusted values with the received data symbols to determine a cumulative error value among adjusted data symbols for each signal filter. The processor uses the data symbols derived by the signal filter having the lowest cumulative error value to demodulate a received data burst.

Abstract: An oxidation-resistant alloy for use in a high-temperature or thermal cyclin g environment. The alloy comprises a nickel-based matrix having a solid soluti on of 19-23 % chromium and 3-6 % aluminum. A self-healing, thermodynamically stable oxide layer is formed upon a surface of the alloy which is exposed to  an oxidizing atmosphere over a range of temperatures for extended periods of  time. The oxide layer protects the alloy from the oxidizing atmosphere. Additions of calcium and yttrium are made to the matrix to substantially remove or stabilize oxygen and sulfur dissolved in the molten alloy. These additions result in retention of about 0.005-0.05 % of calcium and 0.01-0.06  % yttrium in the cast alloy. The matrix further includes about 2-8 % iron to inhibit nucleation and growth of a "gamma prime" nickel aluminum intermetall ic compound which would otherwise adversely harden the alloy and cause local disturbance of a uniform distribution of aluminum. The alloy has a VHN below  about 350.
