Wide-Band Cyclic Cross-Correlation Processing

The wide-band cyclic cross-correlation function (WB-CCCF) is introduced for finite average-power signals. It is the cyclic cross-correlation of a signal and a time-scaled version of another signal. Input-output relationships in terms of WBCCCFs are derived for the wide-band Doppler channel, that is, the channel that introduces a complex gain, a delay, a frequency shift, and a time-scale factor on the complex envelope of the input signal. These relationships are exploited to design new algorithms
