A CDMA communication detector with robust near-far resistance using paralleled array processors

摘要

The code division multiple access (CDMA) scheme has become very popular due to high efficiency for spectrum usage and robust jamming resistance. However, the inherent near-far problem is an impediment. Though deliberate power control algorithms can partially handle this problem, the cost is high. Under the assumption of synchronous symbols and white Gaussian noise, a neural-network-based detector with robust near-far resistance is presented. By proper mapping and applying a hardware annealing technique, compact realization of high precision detectors is possible.
