| Abstract(in English) | This paper presents the frequency diversity effect for block-wised distributed transmission of Layer 1 (L1)/Layer 2 (L2) control signals employing reference signal (RS) based channel estimation in the OFDM downlink broadband channel. In the evaluation, we assume time division multiplexing (TDM) based multiplexing of both the control signal and RS symbols at the beginning of each subframe, and Tail-biting/Terminated convolutional code. By the link-level simulations, we show the loss in the required average received SNR at the average block error rate of 10^<-2> of control signals using RS based channel estimation from ideal channel estimation case. We also clarify the frequency diversity effect for the transmission bandwidth up to 80MHz and the number of blocks for distributed FDMA transmission. Finally, we show the effect of transmit diversity with space frequency block code (SFBC) in addition to frequency diversity derived wider transmission bandwidth and 2-antenna receiver diversity. |
