Embodiment Construction
[0068] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0069] The method of the present invention is based on figure 1 The neural network architecture shown is implemented. The network is composed of an encoding network and a decoding network. The encoding network quantizes the channel matrix into a bit information stream, and the decoding network restores the original channel matrix according to the bit information stream obtained by feedback. The encoding network consists of a composite residual network, a dimensionality reconstruction module, a fully connected network and a 4-bit quantizer. Such as figure 2 As shown, the composite residual network is composed of three rows of different composite convolutions in ...
