The disclosure pertains to fifth generation (5G) or sixth generation (6G) communication systems designed to support higher data rates. A receiver in the communication system comprises a transceiver that can receive a signal encoded using polarization-adjusted convolutional (PAC) coding from a transmitter. Additionally, the receiver includes a controller that is capable of calculating branch metrics of branches defined in a trellis associated with the PAC, determining a path metric based on an accumulated sum of the branch metrics, assigning a path to each state based on the path metric, and estimating a codeword based on the determined path. The number of paths assigned to each state is dynamically determined according to the number of active states, with the active state including at least one branch.
- Receiver in communication system uses PAC coding for signal encoding
