复值Hopfield神经网络盲恢复8PSK信号

传统的神经网络恢复MPSK信号时,因接收信号是复值的,而采用将信号实部与虚部分开盲恢复,该类方法仍存在无法解决的多值信号盲恢复问题.本文利用接收数据正交补投影和发送信号属于有限字符集的先验知识基础上,在异步调整模式下,设计出复值空间的激励函数,将其引入神经网络的能量函数中,推出了一种基于离散复值Hopfield神经网络...

Blindly recovering 8PSK signal with complex-value Hopfield network

The traditional neural network are limited to the complex value signal to recover it by separating signal to the real part and the imaginary part.This algorithms still can not solve the complex-value blind signal recovery problem.The new algorithm change the question of blindly recovering the signals into the one of quadratic optimization with constraints through generalized left null space of received data matrix.Assume that the network has asynchronous dynamics.we design a new complex-value activation fun...
