A method of encoding/decoding using an LDPC code is disclosed, by which performance is enhanced and by which complexity is reduced. In encoding/decoding using an LDPC code defined by an (n-k) xn parity check matrix H, the present invention includes the step of performing the encoding/...
This example shows how to use the pyAerial Python bindings to run 5G NR LDPC encoding, rate matching and decoding. Information bits, i.e. a transport block, get segmented into code blocks, LDPC encoded and rate matched onto the available time-frequency resources (resource elements), all ...
