  • Patent number: 11316540
    Abstract: A method of decoding polar codes based on belief propagation includes conventional belief propagation to decode the polar codes first; when a number of iterations exceeds a predefined upper limit and a cyclic redundancy check fails, the method selects log-likelihood ratio vectors of a plurality of R or L messages from a plurality of log-likelihood ratio vectors generated in each of the iterations and generates another set of log-likelihood ratio vectors (referred to as candidate vector group) to be used as initial values of the R or L messages for a subsequent belief propagation to perform belief propagation decoding iterations and cyclic redundancy check again. Whenever a decoding result passes the cyclic redundancy check, the method exits; otherwise, the method iterates the above procedure until a maximum number of candidate vector groups has been reached.

  • Patent number: 11283652
    Abstract: A communication system and method is disclosed, applicable to the mobile communication using pilot-free channel estimation. In the uplink multiple access, the present invention utilizes the gain division multiple access (GDMA) technology to allow multiple users to share the same resource by utilizing the knowledge of different channel coefficients (channel gains) to distinguish signals transmitted by different users when the transmissions are over different and independent fading channels. Without using pilot signals for channel estimation, the present invention uses the clustering algorithm and the geometrical configuration of the superimposed signals for the superimposed signal sequence received by the base station to implement the estimation of channel gains corresponding to multiple users, and, according to the estimated channel gains, the GDMA technology is utilized to recover the original message transmitted by each user.
