Abstract

Network-assisted diversity multiple access (NDMA) was recently proposed to resolve collision. The blind NDMA method using independent component analysis (ICA) ICA-NDMA, has been developed to overcome the difficulties of synchronization and orthogonal identification codes required by the training-based NDMA protocols. In this paper, we propose a novel blind collision resolution protocol, named as ICA-CoopNDMA, by employing cooperative transmission in ICA-NDMA. When K-node collision happened, a cooperative transmission mechanism is adopted to collect different mixtures of the K original packets in the following slots. After that, the destination can recover the original packets using ICA. This protocol offers spatial diversity by using relay nodes and is robust to the wireless channel. In order to determine the collision multiplicity K, a cooperative blind detection algorithm is also proposed based on minimum description length (MDL) criterion. This algorithm saves one detection slot compared with conventional MDL-based method used by ICA-NDMA. Hence, the delay of ICA-CoopNDMA is reduced. Simulation and theoretical analysis results show that, the proposed protocol can work effectively under both fast and slow fading channels. Compared with ICA-NDMA, the maximum stable throughput and average packet delay are obviously better, and the energy efficiency is higher under heavy traffic load.
