Simulation of LTE downlink system in Simulink

A Simulink-based LTE system simulator. Focus 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 should be implemented. In the receiver, 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 should be investigated. Only considered is the LTE downlink built between 1 base station (eNodeB) and 1 user equipment (UE).I have attached a paper. I want similar kind of simulation where I have to produce my own results and analyse it.
