Architectures for MIMO-OFDM Systems in Frequency-Selective Mobile Fading Channels


Orthogonal frequency-division multiplexing (OFDM) is employed in third and fourth generation and is being planned for fifth-generation (5G) systems. OFDM needs that the received subcarriers be orthogonal. However, numerous factors, like residual carrier frequency offset due to Doppler shift in mobile fading channels, can lead to a loss in orthogonality between subcarriers, that leads to intersymbol interference (ISI), intercarrier interference (ICI), and bit error rate (BER) degradation. In developing the conjugate cancelation (CC) theme for mitigating these ISI and ICI of OFDM systems, we tend to integrate the CC theme together with a house–time (ST) system and kind an STCC multiple-input–multiple-output (MIMO) theme. This STCC system improves the BER while not expending power or bandwidth or complexity. Additionally, a Walsh–Hadamard (WH) rework is utilized as a precoder for this STCC system and forms a unique WHSTCC theme. It provides a coffee peak-to-average power ratio (PAPR) at the transmitter and a vital diversity gain at the receiver. Simulations indicate that both STCC and WHSTCC schemes outperform the regular CC and ST systems in mobile fading channels. Both schemes are simple and are backward compatible, and they will serve as the baseband building block for reconfigurable 5G multiuser MIMO systems.
