+function [distance_v, speed_v] = get_range_speed_val(PRF, fs, fc, numP, gamma_r, gamma_d)
+% Calculates range and speed values for node index
+%
+% Usage: 
+% [distance_v, speed_v] = get_range_speed_val(PRF, fs, fc, numP, gamma_r, gamma_d)
+%
+% Inputs:
+%   PRF:         Pulse Repetition frequency
+%   fs:          Sampling frequency
+%   fc:          Carrier frequency
+%   numP:        Number of pulses
+%   gamma_r:     Range compression ratio(0.5)
+%   gamma_d:     Doppler compression ratio(0.5)
+%
+% Outputs:
+%   distance_v:  Real distance value
+%   speed_v:     Real speed value
