- - IRA SYSTEMS AND METHODS FOR ENCODING AND DECODING OF CHECK-IRREGULAR NON-SYSTEMATIC IRA CODES

摘要

Capacity achieving code is checking of messages in the communication, or electronic systems that require non-uniform non-systems and methods for encoding and decoding the systematic IRA codes are provided. According to these systems and methods, the enhanced IRA coding strategy is employed (non-uniform, low dose error seen a floor - including those employing systemic IRA code box-access ratio). This non-systematic IRA codes are particular channel impairments to half (half) of coded bits (channel impairment) due to the subject to losses and / or complementary to the coding of bits to two or more communication sub-on the channels it transmitted an advantage in the required scenario. The encoder information bit repeater and an encoder, one or more interleavers, the check node coupler, a check node by-pass and includes an accumulator. The decoder comprises a de-mapper, the at least one check node processors, accumulator decoder, a bit decoder and one or more of the interleaver / deinterleaver.;
