초록
Recently, according to the survey, one of the most frequent place to use mobile internet is the moving vehicle, such as bus, subway and train. Therefore, the high speed data rate services for mobile group vehicles moving at high speed are severely required. We design and develop a new system, which can support upto 2.5Gbps data rate services for mobile group vehicles moving at high speed over 400km/h, e.g., KTX (Korea Train Express), TGV (Train a Grande Vitesse) and ICE (InterCity Express), etc. in ETRI (Electronics and Telecommuni-cations Research Institute). In this paper, we propose and design a new structure of the physical layer downlink control channels, and furthermore, we verified the performance of the downlink control channels by computer simulation. Especially, we compared the performance between floating point simulation and fixed point simulation. We verified the performance gap is under 0.5dB. Currently, we develop the test-bed of MHN system and have a target to demonstrate the real time performance of the MHN system on the outdoor environment in 2014. Outdoor demonstration will be done in subway in 1st step. In this paper, we are focusing on the performance of MHN DL control channels, especially on the fixed performance to develop RTL design in test-bed system. We also show the performance of these channels meet the required SNR.
