Interference Suppression in OFDM-Antenna Array with Time Shifted Sampling SUZUKI Hiroki KIZILIRMAK Refik Caglar SANADA Yukitoshi （社）電子情報通信学会 IEICE transactions on fundamentals of electronics, communications and computer sciences 09168508 92 11 2945 2948 2009-11-01 In this letter, an interference suppression scheme by MMSE combining in OFDM-antenna array with time shifted sampling (TSS) is proposed. An array antenna at a base station has been thoroughly investigated to increase the uplink capacity. The performance of the uplink is not only limited by the correlation between the antenna elements, which strongly depends on the spatial aspects of the channel, as well as the interference from the terminals. Numerical results through computer simulation show that the proposed scheme improves bit error rate performance because of interference suppression by MMSE combining and diversity reception by TSS at the same time. 2009-11-01 10026861190 AA10826239 ENG CJP J-STAGE 0 13 Interference Suppression in OFDM-Antenna Array with Time Shifted Sampling SUZUKI Hiroki KIZILIRMAK Refik Caglar SANADA Yukitoshi The Institute of Electronics, Information and Communication Engineers IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences In this letter, an interference suppression scheme by MMSE combining in OFDM-antenna array with time shifted sampling (TSS) is proposed.
