title = "Efficient feedback signaling methods for double STTD in Rayleigh fading channels",
abstract = "We examine efficient feedback signaling schemes in adaptive double space-time transmit diversity (STTD) systems over Rayleigh fading channels. In adaptive double STTD systems, transmit power weights are adaptively adjusted relative to channel fading based on the feedback information. In our paper, the optimum power weights are determined, which are functions of the number of feedback bits and the modulation size employed. We apply symmetric and asymmetric modulation methods in each space-time block encoder in cooperation with adaptive antenna weights. It is shown that the performance of adaptive double STTD with asymmetric modulations depends on the number of available feedback bits, while the same system with symmetric modulations has a relatively robust performance to variable feedback bits.",
