Centralized two-stage modulation classification by using networked sensors

The cooperative operation of multiple networked sensors, due to redundant radio signal reception, allows considerable gain in AMC performance. We here present a cooperative AMC solution with centralized fusion, with suppression of mismatch reference influence through two-step classification process. A performance analysis is performed under the assumed application conditions for dispersive fading channels. Although latest studies indicated that potential gains reported in idealized application conditions are not feasible in practice, i.e. in the non-idealized application conditions, we here demonstrate that these promised gains can be partly achieved with the suitable two-step classifier construction.
