Abstract
In recent years, fifth-generation (5G) is receiving attention in wide research and progress efforts from the wireless communication society. 5G provides a new frequency bands alongside amid the wider spectral bandwidth per frequency channel. To solve the new challenges in 5G, different kind of new modulation techniques and multiple access (MA) schemes have to be adopted. To increase spectral efficiency new techniques called orthogonal multiple access (OMA) and nonorthogonal multiple access (NOMA) techniques are used in 5G wireless system. Here, we propose a class of polyphase sequences called Zadoff Chu sequences which have uniform amplitude, and these sequences bear good correlation properties. Since these sequences are also identified as constant amplitude zero autocorrelation (CAZAC) sequences, Zadoff Chu sequences are used to spread data in OMA and NOMA schemes for 5G networks. The simulation result shows that Zadoff Chu sequence has good correlation properties, and ZCT precoded-based OFDM system is capable of reducing the PAPR significantly.
