Abstract
A linear iterative channel estimation scheme and corresponding pilot allocation scheme are provided to perfect a channel model that cancels the Inter-Carrier Interference (ICI) for multi-carrier systems (e.g., OFDM, SC-FDMA, MC-CDMA, etc.) under high mobility conditions. Two issues of the linear iterative channel estimation scheme of the channel model, namely, overloaded pilots and increased Gauss noise are specifically addressed by exemplary embodiments. With the iterative channel estimation scheme provided by the present invention, the minimum pilot number is equal to the length of multi-path delay, and the Gauss noise is not increased.
