Abstract
The invention relates to a method for channel estimation in a wireless communication system. The communication system includes a communication unit provided with a plurality of antennas, and one or more terminals. First, pilot signals are transmitted from each antenna towards the one or more terminals. At the terminals correlative coding is performed with respect to the pilot signals to form correlatively coded pilot signals. The correlatively coded pilot signals are then retransmitted from the one or more terminals to the plurality of antennas of the communication unit. The communication unit then estimates uplink channels between the one or more terminals and the plurality of antennas based on the correlatively coded pilot signals. Finally, estimates of the downlink channels between the plurality of antennas and the one or more terminals are obtained based on the estimated uplink channels.
