Bit Error Rate Counter (BERC) Class.
Example:
#include <itpp/itcomm.h> int main() { //Initiate the Bit Error Counter BERC berc; //Initiate a Binary Symetric Channel with cross-over probability 0.1 BSC binary_symetric_channel(0.1); bvec transmitted_bits = randb(100); bvec received_bits = binary_symetric_channel(transmitted_bits); //Count the number of bit errors berc.count(transmitted_bits, received_bits); cout << "Estimated bit error probability is " << berc.get_errorrate() << endl; return 0; }

static function to allow simple and fast count of bit-errors
Returns the number of errors between in1 and in2. Typical usage:
bvec in1 = randb(100); bvec in2 = randb(100); double errors = BERC::count_errors(in1, in2);
