  • Abstract
    Rate less codes, such as LT codes, are a class of widely used practical forward error correcting codes. However, conventional LT codes do not make use of feedback information. In addition, owing to the selection of the symbols randomly, conventional LT codes have large redundancy. In this paper, LT codes with limited feedback are investigated. We use several acknowledgment bits to inform the transmitter the most useful symbol for decoding at the receiver side. Transmitter retransmits an input symbol after each feedback to reduce redundancy. Simulation results show that the proposed LT codes can reduce the redundancy significantly and the performance of bit error rate outperform the conventional LT codes.
