Outline of Final Research Achievements

In this study, we consider channel estimation methods for high-speed data transmission in mobile environments. Our final goal is to develop the method to estimate time-variant channels using a few pilot symbols. First, we consider an estimation method for time-invariant sparse channels in OFDM systems with a few pilot symbols. This method combines a deterministic blind channel estimation method and L1 regularization. Next, we extend this method to OFDMA systems and show its effectiveness by computer simulations. Next, we consider an estimation method for time-variant sparse channels using no pilot symbols and show its effectiveness by simulations.
