ADAPTIVE METHOD FOR SELECTING S -RANDOM INTERLEAVER/DEINTERLEAVER
PARAMETERS IN WIRELESS DATA TRANSMISSION SYSTEMS WITH LDPC CODES
Abstract. The S -random interleaver, its application, and the efficiency of its use are
considered. A method for selecting the parameters of an S -random interleaver/deinterleaver in wireless data transmission
systems with LDPC codes under a priori uncertainty was also presented to reduce the complexity of the interleaving/deinterleaving procedure
and increase the reliability of information transmission. The proposed method is shown to provide energy gains for the WiMAX standard.
Keywords: interleaver, data transmission, LDPC codes, decoding, parity-check matrix.
