Accurate time delay is indispensable for many sorts of signal processing applications particular in the field of communication and detection. Traditionally, due to easy operation, interpolation-filter-delay-decimation (IFDD) algorithm was regarded as an intuitive and straightforward way to delay specific signals. However, the computational complexity of this approach will increase sharply with the...
A novel method is presented to estimate sinusoidal frequency from highly contaminated single channel signals by constructing multi-channel surrogates using multiple signal classification (MUSIC) method in frequency domain beam-space (FB-MUSIC). According to the comparability of sampled data in time domain and observed data in uniform linear array, the FB-MUSIC method is proposed and the explicit expressions...
