More than 23% of annual vehicle accidents are rear-end collisions, this gives an important test-case for enhanced collision avoidance approaches based on v2v wireless communications. V2V wireless network concern with the impact of a IEEE 802.11 based multi-hop MAC protocol that propagates an emergency warning message (EWM) down a platoon of cars on a highway. The design objective is to ensure reception...
Code division multiple access (CDMA) systems use the spread spectrum technology to accommodate more number of users without interference and the RAKE receiver concepts to minimize ISI resulting from multipath effects. The ideal approach is to match the number of multipath signals with the number of correlators, but this would be a waste of resources. This paper incorporates a new signal detection...
OFDM based wireless system provides high spectral efficiency but they are very sensitive to Doppler shift. High mobility causes the channel to be fast fading channel. The rapid variation of the channel can induce inter carrier interference (ICI). ICI due to carrier frequency offset can be mitigated by accurate frequency synchronization but ICI due to fast fading channel is more difficult to handle...
Laser communication links in space are attractive alternatives to present-day microwave links. This paper firstly makes an overview of an optical inter-satellite communication terminal. This terminal contains several modules such as transmit assembly, receive assembly, diplexers, mirrors assembly, acquisition and tracking sensor optics, etc. Out of these modules present in the terminal, we proposed...
