volk_32fc_deinterleave_32f_x2

Overview

Deinterleaves the complex floating point vector into I & Q vector data.

Dispatcher Prototype

void volk_32fc_deinterleave_32f_x2(float* iBuffer, float* qBuffer, const lv_32fc_t*
complexVector, unsigned int num_points)

Inputs

- complexVector: The complex input vector.
- num_points: The number of complex data values to be deinterleaved.

Outputs

- iBuffer: The I buffer output data.
- qBuffer: The Q buffer output data.

Example Generate complex numbers around the top half of the unit circle and deinterleave in to real and imaginary buffers.

int N = 10;
unsigned int alignment = volk_get_alignment();
lv_32fc_t* in = (lv_32fc_t*)volk_malloc(sizeof(lv_32fc_t)*N, alignment);
float* re = (float*)volk_malloc(sizeof(float)*N, alignment);
float* im = (float*)volk_malloc(sizeof(float)*N, alignment);
for(unsigned int ii = 0; ii < N; ++ii){
float real = 2.f * ((float)ii / (float)N) - 1.f;
float imag = std::sqrt(1.f - real * real);
in[ii] = lv_cmake(real, imag);
}
volk_32fc_deinterleave_32f_x2(re, im, in, N);
printf(" re | im\n");
for(unsigned int ii = 0; ii < N; ++ii){
printf("out(%i) = %+.1f | %+.1f\n", ii, re[ii], im[ii]);
}
