Abstract
A MAC layer protocol that converts packets into a data stream is presented. The protocol layer accepts packets (like Ethernet packets) and converts them into blocks. The packets may be segmented into multiple hocks and multiple packets or packet fragments may be contained in a block. The blocks contain information for reassembling the data. All blocks may be exactly the same size and format, with the same coding. This allows blocks to be precisely recovered even when some of the bits on the stream have errors on them. The blocks may be interleaved and coded. Each block may be decoded independently of other blocks. The blocks may be numbered, so an ARQ mechanism may request that any missing blocks be resent without asking for a whole packet to be resent. The data stream may be passed to a physical layer like an OFDM or WOFDM stream of data.
