WIRELESS COMMUNICATION SYSTEM FOR A HIGH-SPEED OBJECT THAT MOVES ON A FIXED PATH

摘要

The present invention relates to a method for sending a data signal from a transmitter to a receiver in a multiple antenna wireless communication system. In particular, the method comprises: sending information about the number of transmission antennas of the transmitter to the receiver; receiving from the receiver information about the number of effective communication links of the transmitter and the receiver; determining a precoding matrix based on the information about the number of effective communication links; and receiving from the receiver the data signal using the precoding matrix, wherein transmission antennas of the transmitter and receiving antennas of the receiver respectively form effective communication links independent of each other.
