It is well-known that precoding is an attractive way to remove interferences because it reduces cost and power consumption in the receive equipment. When implementing precoding, however, the base station should know the Channel State Information (CSI) which is normally acquired at the receiver side by using pilot symbols. In Frequency Division Duplex (FDD) systems, this information is sent by means of a feedback channel. In order to reduce the overhead inherent to the periodical transmission of… CONTINUE READING
