An MIMO-OFDM technique for high-speed mobile channels

  title={An MIMO-OFDM technique for high-speed mobile channels},
  author={Kyung Won Park and Yong Soo Cho},
  journal={IEEE Communications Letters},
In this letter, a new orthogonal frequency-division multiplexing (OFDM) technique for multiple-input multiple output (MIMO) channels is proposed to reduce interchannel interference (ICI) caused by high-speed mobiles in cellular environments. After analyzing the ICI caused by high-speed mobile channels using a simple curve fitting technique, the weighting factor for group transmission is optimized. Then, a new MIMO-OFDM technique, based on the weighting factor optimization, is proposed for… CONTINUE READING
