Description

This is an educational simulator for evaluating the downlink performance of the LTE Advanced technology. OFDMA and LDPC codes are employed. Both direct transmission and relaying are considered. This simulator is especially useful for research students working on wireless communication technologies. It is also a useful resource for network engineers to plan for the placement of base station and relay station for a given geographical map. By taping the info button at the top left corner, users can modify the simulation parameters including modulation scheme, node speed, channel model and the number of users. The transmit Signal to Noise power Ratio (SNR) and Path Loss per km can also be edited. User can choose to use the current location as the center of the Googlemap. Alternatively, user can choose to use any other location as well as zooming in and out of the map. When the bottom right button is turned to ON, the Base station (B), Relay node (R) and User nodes (U) will appear on the map. Users can tap the nodes to activate (or deactivate) their movements. The nodes can also be dragged to different locations on the map. The simulator will show the corresponding received SNR (SNRr), distance between B and U as well as the Bit Error Rate (BER). When direct transmission between B and U is poor, a relay node will be employed for Amplify-And-Forward (AAF) the source message from B to U. Cooperative cognitive ratio technology is also employed for investigating the potential bandwidth (BW) saving. The calculation of the BW saved is based on the following IEEE conference paper: W. Liang, S. X. Ng and L. Hanzo, "Adaptive turbo trellis coded modulation aided cooperative cognitive radio", in IEEE Wireless Communications and Networking Conference (WCNC), Paris, 01 - 04 Apr 2012.
