volk_32fc_s32f_x2_power_spectral_density_32f

Overview

Calculates the log10 power value divided by the RBW for each input point.

Dispatcher Prototype

void volk_32fc_s32f_x2_power_spectral_density_32f(float* logPowerOutput, const
lv_32fc_t* complexFFTInput, const float normalizationFactor, const float rbw, unsigned
int num_points)

Inputs

- complexFFTInput The complex data output from the FFT point.
- normalizationFactor: This value is divided against all the input values before the power is calculated.
- rbw: The resolution bandwidth of the fft spectrum
- num_points: The number of fft data points.

Outputs

- logPowerOutput: The 10.0 * log10((r*r + i*i)/RBW) for each data point.

Example

int N = 10000;
volk_32fc_s32f_x2_power_spectral_density_32f();
volk_free(x);
