Shaped Offset Quadrature Phase Shift Keying Based Waveform for Fifth Generation Communication

Fifth generation (5G) wireless networks must meet the needs of emerging technologies like Internet Things (IoT), Vehicle-to-everything (V2X), Video on Demand (VoD) services, Device to communication (D2D) and many other bandwidth-hungry multimedia applications that connect a huge number devices. 5G demand better bandwidth efficiency, high data rates, low latency, reduced spectral leakage. To these requirements, suitable waveform be designed. In this work, namely Shaped Offset Quadrature Phase Shift Keying based Orthogonal Frequency Division Multiplexing (SOQPSK-OFDM) is proposed for provide leakage, Bit Error Rate (BER). The work evaluated using real-time Software Defined Radio (SDR) testbed-Wireless open Access Research Platform (WARP). Experimental simulation results show exhibits BER performance Out Band (OOB) radiation when compared with waveforms (OQPSK) (QPSK) OFDM candidate Generalized (GFDM). analysis shows SOQPSK-OFDM attains Signal Noise Ratio (SNR) gain 7.2 dB at , GFDM in indoor environment. An SNR 8 6 achieved by QPSK-OFDM OQPSK-OFDM signals, respectively. A significant reduction OOB nearly 15 16 Amplitude Modulation (QAM) mapped OFDM.
