| Abstract(in English) | This paper proposes a new linear pre-coding method for multiple amplitude shift keying signals. The proposed linear pre-coding method exploits one constellation dimension of multiple amplitude shift keying (MASK) signals to reduce the unfavorable effect of another user. This pre-coding makes SDMA transmission possible for users with high spatial correlation instead of TDMA transmission of conventional method. This paper explains the detail of the proposed linear pre-coding and presents BER performance by computer simulations. When AP with 2 antennas which accommodates 2 users is assumed and channel model is i.i.d., BER performance is a little superior to that of the conventional method which uses TDMA transmission for users with high spatial correlation. |
