Efficient OFDM Channel Estimation in Mobile Environments Based on Irregular Sampling

We present a novel pilot-aided channel estimation method for OFDM packet transmissions over time-varying channels. The proposed channel estimator is based on 2-D irregular sampling techniques that allow for flexible training data arrangement. The resulting iterative conjugate gradient algorithm invo...
