| 摘 要： | 利用快跳频信号帧间信号一致性以及分布式网络的特点,提出了基于分集合并接收的最小均方误差准则的快跳频多址多用户检测算法.算法适合同步和异步系统,具有较强的抗虚警和抗漏检能力.仿真结果表明该算法能明显提高分布式对等网络终端消除同信道干扰的能力,且相对已有中心功率控制的同步和异步多用户检测算法,该算法可以进一步改善系统的BER性能.

| Abstract: | A multiuser detection(MUD) algorithm based on diversity combining and MMSE for fast-frequency hopping multilevel-frequency-shift-Keying multiple-access communication system is proposed.It exploits the coordinate of signal energy of desired user in the frame and the distribution networks characteristic.The algorithm suits synchronous and asynchronous frequency hopping multiple access communication system,and is capable of resisting false alarm and deletion. Simulation results show that the proposed detector can improve performance of distribution peer-to-peer communication network and cancel co-channel interference.It can also improve BER performance of existent synchronous and asynchronous frequency hopping multiuser detector. |
