Mathews, V. John | An efficient algorithm for lattice filter/predictor | ABSTRACT An efficient method for updating the lattice filter/predictor coefficients using the sign algorithm is introduced. The pertinent coefficients are updated using only the signs of the estimation errors at each stage. This method requires less number of multiplications than other adaptive la... | 1985 | |

Mathews, V. John | Analysis of the short-time unbiased spectrum estimation algorithm | Abstract- The short-time unbiased spectrum estimation (STUSE) algorithm is analyzed and expressions for the mean and variance of the spectrum estimates are derived. The STUSE algorithm deliberately adds biased spectrum estimates in order to yield unbiased estimates and at the same time have excellen... | 1985 | |

Stringfellow, Gerald B. | Organometallic vapor phase epitaxial growth of AlGaInP | Alx Ga,, In, _ x _ y P with x + y = 0.51, lattice matched to the GaAs substrate, has been grown by organometaUic vapor phase epitaxy. The simple, horizontal, IR heated system operates at atmospheric pressure using the reactants TMA1, TMGa, TMln, PH3, and K2. Alloys giving room temperature, band edge... | Liquid phase epitaxial growth; LPE; Alloys; Surface morphology | 1985 |
