Embodiment Construction
[0026] Exemplary embodiments of the present invention will be further described and described in detail below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown, a design method of filter coefficients in the filter forward relay network. The filter forward relay network mentioned in the present invention refers to a half-duplex multi-channel relay wireless communication network, which is composed of a transmitter, a relay node equipped with a filter and a receiver. All channels from the transmitter to the relay node and from the relay node to the receiver are flat fading wireless communication channels. Each relay node is equipped with a finite-length unit impulse response (FIR) filter, which is used to compensate the influence of the flat fading channel on the relay node. figure 1 The superscript "*" refers to the conjugate of complex numbers.
[0028] According to the forward filtering protocol (FF), all relay nodes are equipped with finite-...
