Opportunistic Access with Random Subchannel Backoff (OARSB) for OFDMA Uplink
Abstract— A distributed medium access control (MAC) algorithm for uplink OFDMA networks under the IEEE 802.16 framework is proposed and analyzed in this work. We present a simple...

Mathematical Analysis of Throughput Bounds in Random Access with ZigZag Decoding
— We investigate the throughput improvement that ZIGZAG decoding (Gollakota and Katabi (2008)) can achieve in multi-user random access systems. ZIGZAG is a recently proposed 802....
