/* function which computes the bit allocation from the channel estimation.
The function uses the so called waterfilling algorithm.*/

// inputs: Hreal, Himag, Noise_var
// outputs: bn, en, btot


// function which sort the values gn and return the index
void sort(float *gn, int *Index);


//bit allocation function
void waterfill(float *Hreal, float *Himag, float Noise_var, int *bn, float *en);  //, int *btot);


void waterfill_simple(float *h_hat, float Noise_var, short *bn, float *en, float *gn);
