for K_ind = 1 : length(k) y = goertzel_algo ( dtmf_output,k(K_ind),Num_of_samples) if (K_ind == 1) this appends each Kth array to y1(1 : Num_of_samples) = y( 1 : Num_of_samples) the output array else v_sum = v_sum + Num_of

In practical implementations, the weighting factors for a MRC system are obtained by deriving a signal which has amplitude proportional to the kth branch carrier amplitude and a phase that LMS equalizer
