Resumen:
This paper introduces a block based multiple frequency estimation technique for complex sinusoids in the presence of noise. The proposed adaptive method is based on an all-pass notch filter that works sequentially. The algorithm is adjusted to an off-line operation by repeatedly processing the available block of samples. This results in a low complexity alternative to classic subspace methods such as MUSIC and ESPRIT. A typical application field of the new technique is the carrier frequency offset estimation of multiuser multicarrier modulation
