End To End Physical Layer Design for Efficient Data Transmission in Wireless Communication

Abstract

  In any network designed for data or communication physical layer is the most important layer because it is ultimately depends upon physical layer for any type of transmission. Its importance can be understood by the fact that all the layers of open system interface or transmission control protocol are designed either for serving physical layer or being served by physical layer. The main problems associated with physical layers are attenuation, noise and bandwidth limitations while main responsibilities are end to end efficient and secure data transmission. With the increasing demand bandwidth availability is decreasing while other factors like noise and attenuation is also increasing. In this paper we have designed a physical layer for a wireless channel because on one hand a wireless channel has to face noise, attenuation and bandwidth limitation more severely than its wired counterpart while on other hand and they are most widely in use because of easiness of establishment.
