    55This is a demo of LTE uplink system. The system consists of 1 or 2 users and 1 base station. The users can send different data to the base station. Each user has 2 antennas. Base station also has 2 antennas. For each user, it is a 2x2 MIMO system. The system uses 72 subcarriers for data transmission. In 1-user situation, the user occupies 1~72 subcarriers for transmission. In 2-user situation, each user occupies different part of the bandwidth. The 1st user occupies 1~36 subcarriers, and the 2nd user occupies 37~72 subcarriers.

    99This demo utilizes two WARP nodes, both of which connect to a router. The router is connected to a computer. The computer is used to control the WARP boards and manage the simulation loops.   When starting a simulation in the computer, the simulation script (a MATLAB m-file) will send an image to the transmission node through the Ethernet link. Then the image data will be transmiitted via the wireless link over the air. The receiver node receives the binary sequence and tries to recover the original transmitted image data. Finally, the simulation program in the computer will get the image data via the Ethernet link and then recover the original image.
