摘要：
The performance of low complexity digital direct-sequence spread-spectrum receivers with integrated interference reduction schemes is compared to the analog-receiver and the simple hard-limiter receiver. As interference situation, we assume additive white gaussian noise and strong constant envelope continuous wave interference. An interference reduction scheme, consisting of a special 2-bit nonlinearity with matched magnitude window weighting is employed. The received signal's magnitude distribution and zero-crossings are used to estimate the composition of the interference. By simulation results the proposed adaptive concept is compared to that proposed in [1], which could be described as a robust scheme.
