IPC: H03M13/09
Filed: 2019-10-29
Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may perform blind detection to attempt to receive and decode a polar encoded transmission with unknown transmission parameters. The device may receive a decoding candidate for a codeword and may attempt to decode the candidate according to a first number of information bits. If an error detection check (EDC) fails for the decoding paths resulting from this decoding attempt, the wireless device may extract, from the decoding paths, additional decoding paths of a shorter length. These extracted paths may correspond to a second number of information bits smaller than the first number of information bits. The device may perform an EDC on these extracted paths to determine if any path corresponds to the successfully decoded codeword. This procedure supports reducing the number of decoding processes needed to test different information bit sizes for a codeword.
