Abstract: Convolutionally precoded polar codes known as polarization-adjusted convolutional (PAC) codes are a promising variant of polar codes for short block lengths ...

Abstract: Polarization-adjusted convolutional (PAC) codes enhance polar codes by introducing a rate-1 convolutional pre-transformation. The performance of both polar codes and PAC codes relies on the ...

Communication-system designers have always had to deal with trade-offs among data reliability, efficient use of available spectrum, data throughput, and cost. Error-correction coding (ECC) is one of ...

* Examples of Common Recursive Algorithms. * 1. Time and Space Complexity Analysis: * - Time: Found by analyzing the recurrence relation (e.g., T(n) = 2T(n/2) + O(1)) * - Space: Determined by the ...

FEC (forward-error-correction) techniques correct errors at the receiver end of digital communications systems. In contrast with error-detection and retransmission ...

ABSTRACT: Ultra-wide band (UWB) positioning technology has attracted increasing attention due to its high ranging accuracy. However, in indoor environments, non-line-of-sight (NLOS) signals ...
