... equal for both methods. However, the performance for Method B is slightly degraded compared to that for Method A. This is because the highest amplitude of the CAF for Method B is less than that for ... equal. For example, let us see the case when an equal overhead is paid for Methods A and B. For this case, the detection performance is evaluated based on computer simulation in...
