Design of MIMO F-OFDM System Model for PAPR Reduction in the Growth of 5G Network

A compact 5G technology can be defined as a system which consist of high signal data transmission, maximizing frequency diversity and can combat noise interference. By theory, it is significantly to improve system’s performance in order to obtain better voice quality, tolerance to noise interference, excellent spectral efficiency, higher network capacity, low latency and frequency selective fading in multipath environment, which is robust to the channel impairments. 5G network uses multipath environment or multiple transmissions technique, which known as multiple input multiple output, (MIMO). MIMO operates with multiple antennas technology, which includes the multiple transmitters with receivers’ circuits to minimize errors and optimize data speed. For the transmission efficiency, multiple antenna system model is commonly put together with digital data encoding method called Orthogonal Frequency Division Multiplexer (OFDM), where the carrier signals have high spectral efficiency and immunity to frequency fading. MIMO-OFDM configuration has introduced to increase the diversity gain and improve the system capacity. Currently, filtering is implemented to overcome out-of-band radiation for the spectrum efficiency and meet the diversified expectation for the growth of 5G network. The main drawback in MIMO F-OFDM system is its high peak-to-average-power-ratio (PAPR). This paper discusses the parameter specification in reducing PAPR in MIMO F-OFDM system. The proposed parameters are utilizing block coding technique that is Enhancement Asymmetric Arithmetic Coding (EAAC), together with numbers of antenna configuration to overcome the problem of high PAPR. From the simulation results, the PAPR reduced at 6.85% using block coding technique and MIMO antenna configuration and it is verified with the existing system with MIMO-OFDM. Overall, the communication system model will lead to the mutual harmonization among society with new parameters of MIMO F-OFDM and block coding technique.
