La fonction rand_config() génère aléatoirement une configuration qrand dans l’espace libre. La fonction Etendre permet de sélectionner à chaque itération le noeud de l’arbre G le plus proche (fonction Plus_proche_noeud()) à qrand selon une métrique (distance euclidienne par exemple). La fonction Nouvelle_config() effectue un mouvement dans la direction de qrand avec un incrément Δq. Ce dernier paramètre peut être choisi dynamiquement au cours de l’exécution.

matlab多传感器融合中关于多机器人系统中的目标定位数据融合方法(multi robot position identification in data fusion)

针对OFDM系统，分成链路级仿真和系统级仿真两个部分。为了降低系统级仿真的复杂度，采用链路级仿真的部分结果。(It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate. Link-level simulator support SISO, 1 by x MRC, 2 by 1 STBC/SFBC, 2 by 2 Alamouti, x by 1 Antenna selection, x by y antenna selection. System-level simulator, currently support only SISO and 1 by 2 MRC. To start with, go into the folder sys_link_simu, and excute the following commond from matlab: sys_link_simu_func(a,b) where a is the link ada)
