Abstract

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 pretty 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.
