Rate matching techniques, such as puncturing and shortening, have been developed for polar codes to accommodate the specific code length requirements in practical applications. However, existing shortening techniques cannot be directly applied polarization-adjusted convolutional (PAC) codes. In this work, we propose an approach shorten PAC by imposing constraints on precoding process based patterns. The proposed technique leads up 0.2 dB power gain error correction performance compared...

Belief propagation (BP) decoding of polar codes benefits from the high parallelism in hardware implementation and consequently provides throughput compared to successive cancellation-based algorithms. As evolved log-likelihood ratios (LLRs) process have a wide dynamic range, quantization error can degrade correction performance BP decoder. To reduce uniform scheme, we may need use more bits for each LLR value which is not desirable due required memory space. In this paper, design an...

Convolutional precoding in polarization-adjusted convolutional (PAC) codes can reduce the number of minimum weight codewords (a.k.a error coefficient) polar codes. This result improving correction performance (near) maximum likelihood (ML) decoders such as sequential and sphere decoders. However, PAC cannot be decoded by decoding. The reason is twofold: 1) Sphere decoding performed from last bit - due to lower rectangular shape transform. Whereas generator matrix no longer triangular. 2) One...
