| Abstract: | For the sake of improving the practical system performance by precoding transmission not only at the source terminals but also at the relay nodes for the uplink of the cooperative transmission system,the zero-forcing precoding algorithm was realized.The proposed partial channel precoding scheme based on maximum received signal to noise ratio was introduced to clear the hurdles of low power efficiency of zero-forcing precoding,precoders traditionally used in MIMO system were thus performed into cooperative s... |
