摘要
A method and wireless communication system for identifying one or more undesired signals at a multiple input receive unit receiving a desired signal or several desired signals and the undesired signal or signals. A separability condition between the desired signal and undesired signal is provided to enable that the undesired signal can be identified at the multiple input receive unit. The separability condition includes the use of substantially coherent reception at the receive unit and the use of separable training patterns for the desired and undesired signals. Zero tones are included in desired and undesired signals to further enhance signal separability. Signal training at the receive unit is used to derive the corresponding channel matrices for the interferers and mitigate their effects.
