and number of complex multiplications per sample. According to 1, the approximated MSE for language in mental illness thesis thesis the real valued case is given by where where, (where is the real part of and are the Lagrange multipliers. The interference cancelling ability is dependent on the match between the synthesized waveform, basically the output of a voltage controlled oscillator, and the jamming signal. But, when we deal with a difficult channel (where the initial ISI is considered as very high) and high SNR case, a much faster convergence rate is obtained when using our new proposed Lagrange multipliers over the previously derived set. In this paper, we derive a new set of Lagrange multipliers based on the nonlinear expression for the Lagrange multipliers obtained from minimizing the approximated MSE with respect to the Lagrange multipliers. Next, we wish to find those Lagrange multipliers that bring the MSE ( 8 ) to minimum.

The step-size parameters for the algorithm are defined as and. Taken according. We show in this paper that the new derived Lagrange multipliers are different in sign and magnitude from the recently obtained set. After having described the system under consideration in Section 2, we introduce in Section 3 our new derived Lagrange multipliers for the 16QAM input case. As a matter of fact, the convergence speed of the equalizer with the new proposed Lagrange multipliers ( 13 ) conclusion to banning cigarettes essay is faster with approximately 5000 symbols (the eye-diagram is already open at ) and with over 30000 symbols compared with the equalizer with the previously. New Lagrange Multipliers In this section, we present the Lagrange multipliers for the 16QAM input case that brings the approximated MSE derived in 1 to minimum. In order to find the Lagrange multipliers, a closed-form approximated expression was derived for the MSE where the idea was to bring the MSE to minimum according to the Lagrange multipliers following. The equalizer is a tap-delay line.
