Abstract
A method is provided for use in a cooperative broadcast multi-hop network that employs broadcast flood routing and multi-hop transmission using a direct-sequence spread-spectrum (DSSS) waveform. DSSS signals are received from other nodes on different channels. ASSW is performed to detect and remove interference signals received on the different channels. MDFT analysis banks each receive a beam in the spectral domain that can be channelized to generate a channelized beam that comprises multiple spectral channels. An adaptive interference mitigation space-frequency whitener module can then be applied to remove interference and generate interference-mitigated spatial-spectral domain channels. MDFT synthesis banks can each perform a MDFT synthesis operation on one of the spatial-spectral domain channels. A multi-user RAKE receiver can then combine the interference mitigated time-domain channelized signals to generate a subset (1 . . . F) of fingers that combine components of transmissions directly received from the other nodes and multipath components of those transmissions.
