Optimum Frame Synchronization
This paper considers the optimum method for locating a sync word periodically imbedded in binary data and received over the additive white Gaussian noise channel. It is shown that the optimum rule is to select the location that maximizes the sum of the correlation and a correction term. Simulations are reported that show approximately a 3-dB improvement at interesting signal-tonoise ratios comp...

متن کاملOptimum Mass Matrices for Short Wave Pulse Propagation Finite Element Models
The matrices of a substructure ensuring minimum modal errors of the whole structure are obtained by using optimization approach. The mass and stiffness matrices of a small component domain of selected dimension are obtained by applying the modal synthesis of a limited number of closeto-exact modes such that after assembling a larger joined domain model the modal convergence rate of the latter s...
متن کاملOptimum Frame-length Configuration in Passive RFID Systems Installations
Anti-collision mechanisms in RFID, including current standards, are variations of Aloha and Frame Slotted Aloha (FSA). The identification process starts when the reader announces the length of a frame (in number of slots). Tags receive the information and randomly choose a slot in that cycle to transmit their identifier number. The best performance of FSA always requires working with the optimu...
