Evaluation of LTE-Advanced Networks: The WINNER-II Channel Model Approach with Relay-Enhanced Networks

As a next-generation 3GPP standard, LTE-Advanced exclusively takes the relay technology into account. This book focuses the relay technologies for the LTE-Advanced systems and evaluates the performance of the relay-enhanced LTE-Advanced network. The approach for this work is to design several environments for LTE-Advanced networks involving relays. Incorporating the channel model from the Wireless World Initiative New Radio (WINNER) project, four environments were designed among which one environment considers no relay at all and the rest of the environments considered relay deployments. And the performances of all the environments are evaluated in terms of Symbol Error Rate (SER) versus the Signal to Noise Ratio (SNR), under several different scenarios defined in WINNER project. As an outcome, the simulation results from the simulator show that relay technologies can effectively improve service performance.
