“…Moreover, a synthetic, multichannel periodic signal was used in every simulation with harmonics with unit amplitudes, and, in each simulation, the pitch and DOA were sampled from Hz Hz and , respectively, where denotes the continuous uniform distribution in the interval . The methods evaluated in these experiments are the optimal, white noise, and approximate filterbank ('bo', 'bw', and 'ba') and single filter ('so', 'sw', and 'sa') methods, the multichannel pitch estimator ('am') in [29], the steered response power method with phase transform ('sp') [30], and the exact and asymptotic nonlinear least squares (NLS) methods ('n' and 'an') in [10]. First, the performance of the proposed methods was evaluated for different 's in scenarios with 1) and an SNR of 30 dB, 2) and an SNR of 20 dB, and 3) and an SNR of 30 dB.…”
