      MIMO System Toward 5G Communications.

AB  - Single-sideband (SSB) modulation through Hilbert transformation has successfully 
      transmitted data using only half the bandwidth of the traditional scheme for the 
      same amount of contained information. Toward this end, the four single-sideband 
      (4-SSB) approach for high order modulation is a promising approach for the 
      next-generation communications by applying soft-input soft-output (SISO) 
      equalizer algorithms over orthogonal frequency division multiplexing (OFDM). 
      However, OFDM is challenging for realizing the feasible 5G communications, 
      compared to the emerging techniques, e.g., non-orthogonal multiple access (NOMA), 
      orthogonal multiple access (OMA) or multiple-input multiple-output (MIMO). Since 
      the 4-SSB is an orthogonal modulation which was successfully applied over the 
      traditional OFDM, in this article, we propose a novel 4-SSB modulation scheme 
      over OFDM Guard Interval (GI) and massive MIMO. Besides the carrier signal, from 
      the receiver side, we also apply the shadow equalizer algorithm in the uncoded 
      and coded environment using turbo codes to achieve the 4-SSB with high efficiency 
      from low complexity and energy consumption for 5G. The evaluation results 
      validate that our system consumes lower energy due to low complexity gained from 
      same number of iterations without the heavy decoding as of the 4-SSB SISO based 
      on the turbo equalizer. In addition, the 4-SSB over the OFDM GI achieves the best 
      performance among the relevant approaches conducted in 4-SSB. The proposal then 
      acts as a practical communication system designed to solve the inter-symbol 
      interference (ISI) induced by additional Hilbert transform in the wireless 
      environment toward fifth generation (5G), given that turbo code is considered as 
      a potential channel coding scheme for 5G radio specification.
