Embodiment Construction
[0012] figure 1 It is a schematic diagram of the sending and receiving device of the present invention.
[0013] The specific workflow is as follows:
[0014] 1. The encoder receives the information sequence, and then encodes it using the non-regular low-density parity-check code method.
[0015] 2. The encoding result is output by the encoder and stored in the memory.
[0016] 3. After the information in the memory is sent out, noise is superimposed in the channel, and then reaches the receiver.
[0017] 4. The receiver receives the signal and stores the noise-superimposed signal in the memory.
[0018] 5. The signal enters the decoder for decoding.
[0019] 6. If the decoding is successful, the receiving end sends an acknowledgment signal (ACK) to the sending end through the reverse link, and the memory of the receiving end is cleared at the same time.
[0020] 7. When the sender receives the confirmation signal, delete the contents of the memory, and encode the informa...
