Efficient Real-Time Generation of Bit-Wise Parallel Representations of Oversampled Carrier Replicas

An algorithm has been developed that efficiently generates in-phase and quadrature carrier replicas over a range of Doppler shift frequencies and initial phase offsets. This algorithm provides a new method that aids in bit-wise parallel baseband mixing of signals in software radios, specifically targeted at GNSS radios. Bit-wise parallel correlation, of which one step is baseband mixing, provides ...
