Smart Random Channel Access in OFDM Systems by Joint Signal Processing and Packet Scheduling
Overview OFDM techniques can be exploited to assist random access contention resolution, which can greatly improve random access efficiency. A cross-layer design method is proposed, where the OFDM-based PHysical-Layer (PHY) signal processing and the MAC-layer packet scheduling are jointly designed and optimized. By this method, contentions can be completely resolved. Not only network throughput can be enhanced, but also more stringent QoS requirement may be supported. With the new cross-layer design method, PHY-layer signal detection can be assisted by the MAC-layer smart scheduling, whereas the latter can also be enhanced by the former. The proposed method represents an innovative approach to improve the performance of random access OFDM wireless networks.
