Abstract: A method, performed by at least one processor of a trust broker, for establishing trust of vendor-supplied Open Radio Access Network (O-RAN) software, includes: receiving a plurality of O-RAN software from a plurality of O-RAN software vendors, the plurality of O-RAN software respectively signed by the plurality of O-RAN software vendors; for a software, among the plurality of O-RAN software, verifying a signature included with the software using a vendor certificate issued by a certificate authority (CA) of the corresponding vendor; based on successful verification of the signature, performing a software attestation with respect to the software using a digital certificate issued by a CA of the trust broker; and providing the attested software to an operator corresponding to the O-RAN system and with which the trust broker has a trust relationship.

Abstract: The present disclosure discloses a method and a unit for mapping information bits to polarization angles of a wave for communication. The method comprises transmitting, by a polarization unit of a first communication device, a training signal to a second communication device, for each polarization angle, receiving a feedback signal from the second communication device in response to the training signal, indicating one or more parameters of one or more polarization channels, where each of the one or more polarization channels corresponds to respective polarization angles, categorizing information bits into one or more categories and mapping the information bits to the one or more polarization channels where the mapped information bits are communicated to the second communication device.

Abstract: Embodiments of the present disclosure provide a system and a method for reconstruction of plurality of copies of data packets. The method comprising, receiving plurality of copies of data packets. The method further comprises generating a candidate packet from the plurality of copies of the data packets. Further, the method comprising, selecting at least two probable packets from the plurality of copies of data packets. For bye, the method comprises, receiving confidence factor of the at least two probable packets. Furthermore, the method comprising, determining the one or more common bits to be one of recovered bits and different bits, substituting each of the unrecovered bits of the candidate packet with one of the corresponding recovered bits and different bits of the probable packets. Lastly the method comprises, determining the unrecovered bits of the candidate packet using the packet Cyclic Redundancy Check (CRC) for reconstruction of the data packets.
