Abstract:
To improve spectrum efficiency, 5G necessitates the use of highly sophisticated communication protocols. Because of their enhanced performance, Multiple Input Multiple Output (MIMO) along with Orthogonal Frequency Division Multiplexing (OFDM) have been used. To improve the system's performance, MIMO-OFDM techniques are applied. Because OFDM uses a large number of distinct subcarriers, the signal's amplitude can reach very high peak values. Multicarrier modulation in this form is spectrally efficient. However, the OFDM signal's strong power peaks result in a high PAPR. This high PAPR raises the BER andlowers system performance. With varying route numbers, the Selective Mapping Technique (SLM) employing Complementary Cumulative Distribution Function (CCDF) is highlighted in this paper. When the number of subcarriers is large, SLM is effective. In MIMO-OFDM, the SLM technique can effectively minimise the peak to average power ratio. The fundamental issue with SLM is that it ne
