FPGA implementation of a shuffled iterative bit-interleaved coded modulation receiver
Résumé
Signal Space Diversity (SSD) has been lately adopted into the second generation of the terrestrial digital video broadcasting standard DVB-T2. In this paper, a bit-interleaved coded modulation receiver for the DVB-T2 standard is detailed. An LDPC decoder based on a vertical layered schedule is the main novelty of this work. It enables an efficient exchange of extrinsic information between the rotated demapper and the LDPC decoder if an iterative receiver is considered. The FPGA prototyping of the resultant architecture is then described. Low architecture complexity and good performance represent the main features of the proposed receiver.
