Abstract
Communication plays very important role in day-to-day life of people. Due to fast growing age, multi carrier communication is preferred over single carrier waves for better transmission. One of the advantages of OFDM system over the single carrier system is the better performance in multipath environment. For narrowband operation, one may construct simple amplifiers whose noise figure and power gain are close to the theoretical optima allowed within an explicit power constraint.This paper introduces the design of a 1.5 GHz Low-Noise amplifier using Agilent ADS software. The proposed design aims to provide a better gain of 12.7 dB with low Noise Figure (NF) of 1.76 dB.In this paper we have emphasized on alternative uses of Cellular Automata (CA) in Digital Signal Processing (DSP). The corollary of the distinction is centered on the parallel nature for both of the processors. For digital signal processing, parallelism has been focused with reference to hardware parallelism as well as software parallelism. Major issues for DSP implementation i.e. sampling, superposition, decomposition, Fourier transformation using CA have been covered in this paper [1]. Those discussed results ensure that CA is much efficient to be used for DSP Implementation instead of DSP processors.
