Utilization of Lantana camara can be an effective method for managing the weed. It is of potential economic value as it contains appreciable quantity of cellulosic fibres, have excellent strength properties, but till date not been exploited commercially. Owing to the presence of fibres, L. camara has potential to be utilized for making value added products such as α- cellulose and its derivatives, hand made paper, wood composites (which are good substitute of solid wood depending upon the end use) and furniture. Preliminary studies conducted have shown that Lantana camara contains ∼66 % holocellulose and ∼27% lignin. The average fibre length is 912μ with fibre diameter ∼22μ. α-Cellulose was isolated from L. camara with product yield ∼40%, brightness ∼80% at ∼95% purity having negligible ash content. α-Cellulose isolated from L. camara was derivatized to prepare water soluble carboxymethyl cellulose (CMC) having DS of 1.22, viscosity 600 cps (1% solution) and 7500 cps (2% solution).

A Software Defined Radio (SDR) is a reconfigurable radio, in which channel modulation waveforms are defined in software. In this paper Software Defined Radio (SDR) 4-bit QAM Modem for Gaussian Channel is implemented using abVIEW software. LabVIEW is a graphical development environment with built-in functionality for simulation, data acquisition, instrument control, measurement analysis, and data presentation. The aim of this paper is to simulate SDR for next generation wireless communication having Gaussian channel and Adaptive Filter is used to remove Gaussian noise present in received signal and minimize the effect of Intersymbol Interference. It is obvious from the Simulation results that SDR is suitable for Gaussian channel giving Optimum Performance.
