A Closed-Loop STTD Scheme using Limited Feedback Unitary Precoding for MIMO-OFDM-OSTBC System

摘要：

In this paper, we present a closed-loop STTDscheme using limited feedback unitary precoding for MIMO-OFDM-OSTBC systems, which supports different numbers oftransmit antennas. The simulation results show that adoptingthe STTD scheme in MIMO-OFDM-OSTBC system can obtainhigher diversity advantage. Compared with other STTDschemes, the proposed scheme is more flexible in practicalapplication, allows a tradeoff between feedback rate andsystem performance, and has good upgrading ability ofsupporting the systems with different numbers of transmitantennas.
