A polycrystalline LaAlO3 target for the radio-frequency (rf) magnetron sputterings of LaA10, thin films has been prepared. These films serve as a buffer layer for high-l;. YBa2Cu307-, superconducting thin films on Si. Synthesis of lanthanum aluminate powder from a mixture of La203 and AI2O3 powders was performed by calcining from 1000" to 1600°C in air. Characterization of the calcined powders by X-ray diffraction indicates that full development of LaA10, phase was evident in the sample calcined for 3 h at 1600°C in air. A polycrystalline LaA103 target was prepared by heat treatment at 1500°C for 2 h in air after pressureless sintering at 1750°C for 3 h in Ar. Thin films of the LaAlO, on Si (100) were obtained by rf magnetron sputtering using the target and oxygen-annealing the as-deposited films. [

In this paper, the complexity of Viterbi Architectures is compared in the point of the survivor sequence management. Moreover, the Viterbi Decoder with Constraint length(K=7), Truncation length(T=5K), and Code rate(R=1/3) is implemented. The Viterbi Decoder uses the Radix-4 as the ACS method to obtain high throughput and low latency. The Modified State Mapping algorithm is also applied to achieve low latency as the survivor sequence management.
