| 摘 要： | 提出了适合无中心控制的对等网络的盲空时自适应干扰消除算法．本算法利用检测信号功率恒定的特点，采用了两个滤波器组，当其中一个工作时，另一个开始调整权系数，从而提高了收敛速度，避免了跳频频率变化带来的波束估计误差．仿真结果表明，提出的盲自适应算法可以明显提高输出信号SINR增益．

| Abstract: | A blind space-time adaptive multi-access interference algorithm for FFH-MA/MFSK systems peer to peer network was proposed.Which utilize use two filter group and constant power algorithm to increase convergence,when one filter in the information hopping bins,while the other filter starting adjust weighing factor and estimate interference and noise power.Consequently,it could avoid the error of beam estimate because of frequency hopping.The simulation result show that proposed adaptive algorithm has improved distinguishably the output SINR. |
