Abstract

PARTICULAR CODEBOOK ENTRIES USED FOR A MIMO SYSTEM OF A LOWER DIMENSION (I.E., HAVING A RELATIVELY LOW NUMBER OF ANTENNAS) CAN BE USED TO GENERATE A CODEBOOK FOR A MIMO SYSTEM OF A HIGHER DIMENSION (I.E., HAVING A RELATIVELY HIGH NUMBER OF ANTENNAS). THE ENTRIES IN RANK 1 OF THE CODEBOOK RELATED TO THE MIMO SYSTEM HAVING FOUR TRANSMIT ANTENNAS ARE USED TO NEWLY CONSTRUCT ENTRIES FOR RANK 1 THROUGH RANK 8 OF TWO BASE MATRICES FOR A MIMO BASE CODEBOOK RELATED TO EIGHT TRANSMIT ANTENNAS.
