Abstract
In this paper, the effects of various analog front-end impairments on the estimation of channel response for OFDM based wireless communication systems were discussed. Then, channel estimation algorithms that can take these effects into account were suggested. It was shown that the analog-front end impairments affect the performance of channel estimators greatly. However, with careful channel estimation algorithm designs, these effects can be minimized or completely compensated.
