摘要

Interleavers were made a part of the digital communication to tackle the presence of burst errors due to a noisy channel or incorrect viterbi decoding by performing a rearrangement of the bits by using an interleaving array of size Nr × Nc where Nr is the number of rows, also called interleaver depth and Nc is the number of columns of the array. A typical audio and video broadcasting system consisting of a Linear Block code (LBC) and a block interleaver is presented and a method to deinterleave the received sequence without any knowledge of the blocks used on the transmitter side i.e. in a blind setting is discussed. There is hardly any existing literature that solves this problem completely. The proposed algorithm calculates Nr and codeword length by using rank deficiency while Nc is calculated by using cyclic convolution to complete the analysis that is conducted on different LBCs with varying frame structure formats.
