Code Division Multiple

Mesh Networks are employed in various applications despite issues relevant to interference and network capacity. These networks also impose delay in routing and reconfiguration. Traditionally, TDMA and FDMA techniques have been used in these networks. This paper proposes wideband code division multiple access (WCDMA) technique for enabling maximum power transfer, low energy consumption, interference free and plug-and-play feature enabling easy implementation of the technology. The spatial configuration and node count bounds are stated ensuring continuous satisfaction of quality of service by the communication link. Additionally, dynamic parallel orthogonal transmission and turbo coding schemes are used in combination to improve the efficiency of the network even for large hop counts.

There are large amounts of cars passing through the streets every day and this increases significantly in the morning or evening rush hours. The automotive industry has evolved greatly and many technologies have been introduced to automate many of its functions. The code division multiple access(CDMA) is mostly used in our daily lives. The emergence of driverless vehicles has led to a boom in the world of automotive technology, because of its importance in creating a new environment and new concepts aimed at human conformability and increased productivity. Many solutions have been appeared to offer suitable self-driving vehicles environment that is capable to overcome the arising problems. When the self-driving vehicles are well equipped, the only remaining goal is how to control external communications with other vehicles, with updates that can appear in the road and with main center. It come through by the help of CDMA network connection. This paper proposed code division multiple access as a communication technology to overcome the problems may appeared in time division multiple access.The proposed system of robot cars is implemented through high way environment scenario. The communication system is implemented via code division multiple access (CDMA) to realize high security, high quality of services, robustness and high capacity.
