Statistical Multipath Signal Detection in CDMA for Ad hoc Network

Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, ‘‘ad-hoc’’ network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is not a new one, having been around in various forms for over 20years.Ad Hoc networks are multi-hop wireless networks where nodes may be mobile. These types of networks are used in situations where temporary network connectivity is needed. Ad hoc networks are formed on a dynamic basis, i.e. a number of users may wish to exchange information and services between each other on an ad hoc basis, in order to do this they will need to form an Ad Hoc network. Multipath signal detection is done using BPSK for CDMA Extended for OFDM and calculated the BER and that signal is analyzed in Ad hoc Network.
