  • In [4], ici self-cancellation of the data-conversion method was proposed to cancel the ici caused by frequency offset in the ofdm system in [5], self ici cancellation method which maps the data to be transmitted onto adjacent pairs of subcarriers have been described was not bandwidth efficient.
  • Performance of ici cancellation in ofdm system using different reduction techniques m 2tejeswara rao1, i krishna rao 1.
  • In addition, statistical approaches have also been explored to estimate and cancel ici (tiejun , proakis, and zeidler, 2005) in this paper the ofdm system is modeled and simulated under awgn channel we are concerned with combating the effects of ici induced by cfo, presented the ici self- cancellation scheme algorithm to combat ici effect.

Since ofdm is very much sensitive to carrier frequency offsets, which cause the inter-carrier interference (ici) leads to mitigation of this ici is necessary the objectives of this paper are to.
