In the current context, Orthogonal Frequency Division Multiplexing (OFDM) technology has evolved into OFDM-IM, which is recognized for its superior BER efficiency when compared to OFDM. Our investigation has revealed superior BER performance of OFDM-IM, particularly in single input single output (SISO) configurations under AWGN noise. Our subsequent objective is to scrutinize the performance of OFDM-IM in multiple input multiple output (MIMO) scenarios, employing Millimeter-Wave (mm-Wave) channel mediums with various types of fading. In summary, this assessment offers valuable insights into the performance of both OFDM and OFDM-IM systems under AWGN conditions, shedding light on the advantages that OFDM-IM may bring to forthcoming communication systems.

摘要

In the current context, Orthogonal Frequency Division Multiplexing (OFDM) technology has evolved into OFDM-IM, which is recognized for its superior BER efficiency when compared to OFDM. Our investigation has revealed superior BER performance of OFDM-IM, particularly in single input single output (SISO) configurations under AWGN noise. Our subsequent objective is to scrutinize the performance of OFDM-IM in multiple input multiple output (MIMO) scenarios, employing Millimeter-Wave (mm-Wave) channel mediums with various types of fading. In summary, this assessment offers valuable insights into the performance of both OFDM and OFDM-IM systems under AWGN conditions, shedding light on the advantages that OFDM-IM may bring to forthcoming communication systems.
