An RF Channel Emulator-Based Testbed for Cooperative Transmission Using Wireless Sensor Devices

In this paper, the issues and methods regarding setting up the testbed for measuring the performance of cooperative transmission is introduced. Also, some experiments on both the testbed and the performance of cooperative transmission is introduced and discussed. This testbed is novel in the sense that it uses actual sensor devices along with the channel emulator, which allows us to emulate the exact channels we want without looking for suitable channel environments. We consider the two- hop relay network for our target network model, and cooperative transmission scheme we have selected is decode-and-forward fixed relaying scheme introduced.
