Abstract
A channel estimation device is provided to achieve high-precision channel estimation in a MIMO or multicarrier wireless receiver. This channel estimation device is used in the wireless receiver that receives pilot signals through reception antennas. The pilot signals are modulated by a multicarrier method and are transmitted from transmission antennas. The pilot signals are orthogonal to one another. The channel estimation device includes: an estimation unit that determines a channel estimate value for each unit time slot and each unit sub carrier; and an averaging unit that averages the channel estimate values over time slots including a target time slot and sub carriers including a target sub carrier, thereby determining an average channel estimate value.
