  • Patent number: 11765086
    Abstract: Embodiments include radio transmitters, receivers and methods of operation for enhanced bandwidth utilisation. The transmitter hashes received data blocks to produce indices associated with the received data blocks. The data blocks and associated indices are stored in memory and transmitted. If the received data blocks have previously been stored, the indices are transmitted instead of the data blocks. The receiver stores the received data blocks and associated indices in memory, and outputs the received data blocks. When the receiver receives indices instead of data blocks, it accesses the memory to look up and retrieve the associated data blocks, and outputs the retrieved data blocks.
