| Abstract(in English) | In this article, we study time-domain equalization to suppress inter-symbol interference in OFDM transmission without CP. We propose a blind equalization method which determines a liner equalizer without pilot symbols. We show theoretically that zero-forcing equalization with an arbitrary equalization delay can be achieved. We also propose two modified methods: an equalization delay determination method even with imperfect synchronization; an improvement method using an equalization output power constraint. Simulation results show that a proper equalization delay provides a significant performance improvement. It is also shown that the proposed equalization delay determination method and the use of power constraint are effective. |
