An effective technique for increasing capacity and improving bandwidth in 5G narrow-band internet of things

<p>In recent years, the wireless spectrum has become increasingly scarce as demand for services grown, requiring imaginative approaches to increase capacity within a limited spectral resource. This article proposes new method that combines modified symbol time compression with orthogonal frequency division multiplexing (MSTC-OFDM), enhance narrow-band internet of things (NB-IoT) system. The suggested method, MSTC-OFDM, is based on (MSTC) technique. MSTC compressed waveform technique increases by compressing occupied without losing bit error rate (BER) performance or data throughput. A comparative analysis provided between traditional (OFDM) system and MSTC-OFDM method. simulation results show scheme drastically decreases (ST) 75% compared standard OFDM As result, offers four times typical using same bandwidth modulation but little in complexity. Moreover, an 16 quadrature amplitude (16QAM-OFDM), reduces signal-to-noise ratio (SNR) 3.9 dB transmit amount data.</p>
