Class A雑音環境下における スキャッタードパイロットシンボルを用いた伝送路推定に関する研究

In OFDM, one of the issues is the influence of the impulsive noise in the channel. In the compensation of impulsive noise, it is necessary to estimate the channel. In conventional channel estimation scheme has low performance of time domain and it is issue that estimation accuracy in time varying channel such as Rayleigh fading. Therefore, channel estimation scheme using time sample replacement scheme adapted for scattered pilot symbols is proposed in this paper. By computer simulations, the proposed scheme can achieve better characteristics than the conventional scheme.
