Combining Co-operative Diversity in Wireless Communication
Abstract: Wireless devices cannot employ Multiple Input Multiple Output (MIMO) due to hardware or size limitation. Wireless device should replicate their single antenna virtually to act like MIMO system for better performance. This process is possible through a new system known as co-operative communication. In this system, the terminal or nodes combined to transmit the signals to follow an antenna array and form the diversity. Diversity is nothing but transfer of …

Application of Wavelet De-noising for Wind Speed Retrieval from a 2.5 MHz Partial Reflection Radar
Abstract: Atmospheric studies related to middle-atmospheric coupling, climate monitoring, steering profiles for expendable launch vehicles and re-entry missions require atmospheric wind profiles as an important input. Atmospheric wind profiling is conventionally carried out using rawinsondes and radiosondes flown in high altitude balloons, complemented by sounding rockets and ground-based radars. The partial reflection radar (PRR) can be effectively used for the same purpose to an altitude of about 100 km. But deriving …

Analysis of Speech Using Different Methods
Abstract: In speech analysis, the voiced-unvoiced decision is usually performed in extracting the information from the speech signals. In this paper, two methods are performed to separate the voiced and unvoiced parts of the speech signals. These are zero-crossing rate (ZCR) and energy. In here, we evaluated the results by dividing the speech sample into some segments and used the zero-crossing rate and energy calculations to separate the voiced and unvoiced …

Impact of Storage Methods and Duration on Sugar and Starch Content and Ethanol Yield of Sweet Potatoes [Ipomoea batatas (L.) Lam]
Abstract: Previous studies have shown that ‘industrial’ sweet potatoes can be an excellent feedstock for ethanol production as compared to corn, sorghum and other potential feedstocks. However, starch content can be affected by cultivars as well as storage conditions. Ideally, it is practical that sweet potato storage roots be processed for ethanol production as close to harvest as possible, but this may not always be the case and some amount of …
