摘要：
An apparatus for estimating a wireless radio channel between a first terminal and a relay station, the apparatus including a receiver for receiving a signal including a superposition of previously transmitted first information from the first terminal and second information from a second terminal, the second terminal also communicating with the relay station, a storage for storing the previously transmitted first information, and a channel calculator for calculating the wireless radio channel using the received signal and the stored first information as pilot information for the received signal.
