Abstract


Nowadays, fifth generation (5G) wireless network is considered one of the most important research topic in wireless industry and it will be substituting with fourth generation (4G) in several aspects. Although the robustness of orthogonal frequency division multiplexing (OFDM) system against channel delayed which is the reason behind using it in LTE/LTE Advanced however, it is suffering from high Peak to Average Power Ration (PAPR) and out of band side lobes. So, universal filtered multi-carrier (UFMC) technique is considered as new modulation scheme for emerging 5G wireless communication systems to overcome on the known OFDM demits. In contrast, to achieve the reliability in data transmission for digital communication systems, using error correcting codes are considered an essential over noisy channels. So, BCH codes have been used in this paper for UFMC system over AWGN. The results showed that using BCH codes in UFMC contributed in enhancing BER performance while could decreasing both of PAPR and OOBE values better than OFDM system. Where, PAPR for OFDM system was 9.9269 dB while it was 8.6229 dB and 8.6899 dB for Uncoded and BCH codes with UFMC system respectively. Furthermore, the OOBE level of UFMC system was around 40dB lower than OFDM system.
