Complex LMS

Module by: Douglas L. Jones. E-mail the author

LMS for complex data and coefficients (such as quadrature communication systems) takes the form y k = W k H ⁢ X k y k W k H X k e k = d k − y k e k d k y k W k + 1 = W k +2⁢μ⁢ e k * ⁢ X k W k + 1 W k 2 μ e k * X k It is derived in exactly the same way as LMS, using the following complex vector differentiation formulas dd W P H ⁢W=0 W P H W 0 dd W W H ⁢P=2⁢P W W H P 2 P dd W W H ⁢R⁢W=2⁢R⁢W W W H R W 2 R W or by differentiating with respect to the real and imaginary parts separately and recombining the results.
