Keywords:Trellis code, turbo code, error correcting code, PAPR, BER, OFDM
In the era of wireless communication, internet devices such as smart phones, hotspots, and Wi-Fi zone are important player of rapid growth of data usage. Internet connection devices are building new challenges for internet service providers such as higher bandwidth and indomitable increasing users day to day. The focus of 5G technology is to accomplish high data rate (10-12 Gbps). For this a huge bandwidth is needed. Since limited frequency resources are available, the frequency spectrum should be efficiently utilized to obtain high data rate. OFDM is used in 4G communication but it has the drawback of low spectral efficiency and high out of band radiation, which makes it a poor choice for 5G communication. In this thesis error correcting code trellis code is used for 5G communication. High PAPR is always a problem in multicarrier communication system. 5Gis also a multicarrier communication system, so it also suffers from high PAPR problem. To reduce the PAPR several PAPR reduction techniques have been proposed over the last few decades. Clipping techniquesgives good result and it is used for reduction of PAPR in system. In this paper a combined scheme of error correcting code and clipping technique using compressive sensing are used, which gives significant performance improvement compared than other techniques. Simulation is performed to analyses the PAPR and BER performance of proposed system. All the simulations are performed in MATLAB.
