Abstract (en)

[origin: WO9950990A1] The present invention discloses a method and system for interleaving blocks of a packet to minimize the effects of burst errors and at the same time enhance the effectiveness of the ARQ protocol. A packet is first divided into a plurality of blocks. Each block is then individually encoded and inner-block interleaved. Thereafter the blocks are interleaved over a longer time period. By performing two stages of interleaving, the present invention allows for the size of a packet block to be kept at a minimum, which increases the effectiveness of the ARQ protocol, and provides greater interleaving of the packet's data elements so as to minimize the effects of burst errors.
