MULTI-CHANNEL SELF-INTERFERENCE CANCELLATION METHOD AND APPARATUS FOR RELAYED COMMUNICATION |
摘要 |
Multi-channel self-interference cancellation is provided in relayed electromagnetic communication Fig. 4 between a first device and one or more other devices on one or more shared frequency channels. Specifically, near signals are generated at the first device and transmitted to a relay station. A composite signal is received at the first device from the relay station containing relayed versions of the near signals and relayed versions of remote signals transmitted from the one or more other devices, the composite signal having frequency channels including the one or more shared frequency channels, each shared frequency channel occupied by at least one of the relayed near signals and one of the relayed remote signals. One or more cancellation signals are selectively generated, each having a frequency band corresponding to one of the shared frequency channels. The cancellation signals are combined with the composite signal to produce a desired signal representing the relayed remote signals.
