1	Role of Diversity in Wireless Communication Enhancement- A Review Sagar Jain, Anand Vardhan Bhalla Abstract - In wireless communication, a diversity scheme refers to a method for improving the reliability of a message signal by using two or more communication channels with different characteristics. Diversity is mainly used in communication and is a common technique for combatting fading and co-channel interference and avoiding error bursts. It is based on the fact that individual channels experience different levels of fading and interference. Multiple versions of the same signal may be transmitted and/or received and combined in the receiver. Alternatively, a redundant forward error correction code may be added and different parts of the message transmitted over different channels. It is the technique used to compensate for fading channel impairments. Diversity is usually employed to reduce the depth and duration of the fades experienced by a receiver in a flat fading channel. These techniques can be employed at both base station and mobile receivers.	Download
2	Growth, Morphological, Structural, Optical and Compositional Analysis of Zinc Sulphide Thin Film by Dip Coating Method K. Ravikodi, K. Ramkumar Abstract - In this exposure, ZnS thin film has been achieved with purity using zinc nitrate and thiourea as starting precursors. Deposition time behaviour of ZnS on glass plate was studied by morphological study. XRD reveals the sample’s crystalline nature and the structural parameters. Optical investigation gave information about the prepared sample. To check the chemical composition of the sample an energy dispersive X-ray (EDS) spectroscopy analysis was preformed.	Download
