System and method of coding cyclic redundancy check bits to enhance frequency reuse in a communications network |
摘要 |
A system and method are provided for masking messages intended for a particular one of a plurality of receivers receiving messages on the same frequency in a satellite communication system. Each message contains a data portion and a parity portion. Before transmitting the message, the parity portion is masked by performing an exclusive-OR operation on the parity portion using a mask identified with the intended receiver. At the receiver, the parity portion of received messages are first unmasked by performing an exclusive-OR operation on the masked parity portion. The message is accepted by the receive only if the parity check is valid after the unmasking operation.
