Simulink based LTE system simulator

A MATLAB Simulink-based simulator for an antenna system has been developed at Chalmers, followed by the implementation of a WCDMA system in it. Naturally, 3GPP LongTerm Evolution (LTE) as a new standard for communication system should be considered next. Therefore, a Simulink-based LTE system simulator connected to the existing antenna blocks and WINNER channel is presented in this master thesis. It focuses on the implementation of the LTE downlink in the physical layer. In the transmitter, functionalities like Turbo coding, rate-matching, MIMO (up to 4×4) and OFDM are realized. In the receiver, ideal and non-ideal receiver algorithms are supported, including two types of channel estimation, linear equalizer, Turbo decoding, PMI calculation and HARQ functionality. The results, such as raw bit error rate, bit error rate, block error rate and user throughput are studied in the simulator for different system settings.
