摘要: A new interference self-cancellation (ISC) method for Single Carrier-FDMA (SC-FDMA) systems is proposed to mitigate the inter-user caused by frequency offset or Doppler effect. By transmitting a compensation symbol at first location in each resource block, energy leakage can be significantly suppressed. With little bandwidth and power sacrifice, greatly improve system robustness against offset. Simulation results show that signal-to-interference ratio (SIR) improved 7 dB on average entire band, up 11.7 an individual user.
