*
* Volk protokernel that performs the carrier wipe-off mixing and the
* Early, Prompt and Late correlation with 64 bits vectors (32 bits the
* real part and 32 bits the imaginary part):
* - The carrier wipe-off is done by multiplying the input signal by the
* carrier (multiplication of 64 bits vectors) It returns the input
* signal in base band (BB)
* - Early values are calculated by multiplying the input signal in BB by the
* early code (multiplication of 64 bits vectors), accumulating the results
* - Prompt values are calculated by multiplying the input signal in BB by the
* prompt code (multiplication of 64 bits vectors), accumulating the results
* - Late values are calculated by multiplying the input signal in BB by the
* late code (multiplication of 64 bits vectors), accumulating the results
