CHANNEL ESTIMATION SIGNAL DESIGN METHOD FOR MASSIVE ANTENNA ARRAY SYSTEM

摘要

The present invention discloses a channel estimation signal design method for a massive antenna array system. The method includes the following steps: calculating a matrix (U) comprising eigenvectors and a diagonal matrix (Λ); calculating a solution (X^*_l) to a problem about designing a channel estimation signal; designing as many column vectors as the number of length (T_t) of a channel estimation signal; designing a channel estimation signal matrix (^~S^~_ι) by using the designed column vectors; transmitting a value (U S ^~_ι) obtained by multiplying the matrix comprising the eigenvectors and the designed channel estimation signal; and transmitting a value obtained by multiplying the transmitted matrix and the channel estimation signal.;COPYRIGHT KIPO 2016
