The Fourier Linear Combiner algorithm. The adaptation of the coefficients w k is performed based on the least-mean-square (LMS) recursion. y k is the input signal. The adaptive weight vector, W k , generates a linear combination of the harmonic orthogonal sinusoidal components of the reference input vector, X k . M is the number of the harmonics used and μ represents the amplitude adaptation gain used for the LMS recursion.
