Signal with power-law group delay.
[X,GPD,F]=GDPOWER(N,K,C)
number of points in time (must be even)
degree of the power-law (default : 0)
rate-coefficient of the power-law group delay. C must be non-zero. (default : 1)
time row vector containing the modulated signal samples
group delay (length : round(N/2)-1)
frequency bins
generates a signal with a power-law group delay of the form tx(f) = T0 + C*f^(K-1). The output signal is of unit energy.
