The PAPR of CAMC is very low since the amplitude has a constant value, which is accomplished at the cost of redundant bits for the precoding in CAMC. We show, however, that redundant bits in CAMC can be reconfigured into parity bits in a single parity check product code (SPCPC). An ...
在5G Polar code 中,我们已经知道, CRC 级联 Polar code 来使用,但是,在短码的时候,也引入了 PC ( Parity Check) ,对 polar code 使用 PC 校验的理论分析,在论文 [1] 中有论述,我们这个文章主要看看 5G NR 中如何生成这个 PC 比特数据的。 上层原始数据,通过计算 CRC ,额外附加了 CRC 校验比特, CRC ...
As a generalization, the PCC polar codes differ from the CRC-concatenated polar codes in two major aspects: (i) parity-check codes are more general than CRC codes, which makes more room for better code construction; (ii) the parity bits are allowed to be scattered within the unfrozen bit ...

Now we discuss an advanced form of Block Codes known as Low Density Parity Check (LDPC) codes. These codes were first proposed by Robert Gallager in 1960 but they did not get immediate recognition as they were quite cumbersome to code and decode. But in 1995 the interest in these codes ...

as the “parity-check matrix” of the code C (n, k) and every codeword c ∈Γ must satisfy the following relationship: H· c T = 0, (2.7) where 0 represents the null vector with size r × 1. In other terms, Eq. (2.7) means that every codeword c ∈Γ must verify r parity...
