It is necessary to have a new and enhanced waveform system for transmission that is compatible with the band in order to accommodate the forthcoming 6G mobile network. Due to the fact that orthogonal frequency-division multiplexing (OFDM) is frequent wave form in 4Generation LTE & 5Generation new radio (NR) for enhanced mobile broadband or eMBB transmission of data on multicarrier, it is very probable that a more advanced version of OFDM will be developed for elsewhere 5G (B5G) along with the 6G mobile message scheme. In orthogonal frequency division multiplexing (OFDM), several orthogonal subcarrier indicators through overlapping frequencies remain sent nearby in order to transport data simultaneously. The methods of FAST Fourier transform are the foundation upon which demodulation is built. For the purpose of altering every subcarrier (the signal) at a low symbolic rate, a conventional modulation approach, such as quadrature amplitude variation or else phase change keying, is used. As long as the bandwidth remains the same, this ensures that the overall data rates remain the same as they would be with conventional single-carrier modulation techniques. By altering the number & indexing of active subcarriers that for every OFDM subblock, a new transmission technique has been devised. This approach is capable of transmitting a greater amount of information. There is a difference between OFDM-HNIM, OFDM-SNM & OFDM-IM when compared to itself. This mixed modulation approach is superior to previous OFDM modulation systems in terms of both the spectrum & energy economy that it offers. When it comes to lower modulation rates, such as BPSK, which may deliver great dependability while still being very simple, this is particularly true. It is possible to employ this modulation approach for systems that need improved energy as well as spectrum economy, strong reliability, and minimal complexity among their requirements. In addition to flow and the greatest feasible rate, it pr
