Abstract :
We propose a multicode multicarrier random access protocol for wireless LANs that builds upon earlier work in blind network-diversity multiple access (B-NDMA) for packet radio. B-NDMA guarantees blind separation of users\´ packets with virtually no throughput penalty. The proposed scheme allows users to transmit multiple packets per channel slot, each modulated by a random digital "retransmission carrier". This incurs no throughput penalty and attains significantly lower delay, while maintaining the blind collision resolution capability of B-NDMA.
