[ratings] Random Interleaver: The Random Interleaver rearranges the elements of its input vector using a random permutation. The incoming data is rearranged using a series of generated permuter indices. A permuter is essentially a device that generates pseudo-random permutation of given memory addresses. The data is arranged according to the pseudo-random order of memory addresses. … Read more
Reed-Solomon (RS) codes are powerhouse error-correcting tools, but they have a specific Achilles’ heel: if a burst error exceeds their correction capacity ($t$), the entire codeword fails. Block Interleaving is the mathematical bridge that allows RS codes to survive massive, contiguous bursts by spreading the damage across multiple codewords. This comprehensive guide explains the design, … Read more
[ratings] Interleavers and Deinterleavers are designed and used in the context of characteristics of the errors that might occur when the message bits are transmitted through a noisy channel. To understand the functions of an interleaver/deinterleaver, understanding of error characteristics is essential. Two types are errors concern communication system design engineer. They are burst error … Read more
