This paper presents a hierarchical fuzzy logic canceller
that suppresses digital and/or analog interference from a CDMA
signal. The optimum filter to remove them is the Conditional
Mean Estimator (CME) or the MAP detector of the interference.
The CME and MAP, however, present a high computational
burden which difficult their feasibility. To overcome this
drawback, we propose a hierarchical fuzzy canceller that is
beneficial in terms of computational load. Finally, asymptotic
studies of the Signal to Interference plus Noise Ratio
improvement (SINR) and the working region of the fuzzy
canceller have been carried out.
