Abstract

In digital communications, a nonlinear-phase communication channel needs to be equalized by using a phase-equalizer in such a way that the nonlinear-phase can be compensated and thus the whole communication channel has nearly linear-phase. As a result, the transmitted signal waveform will not be distorted. This paper proposes an improved iterative second-order-cone-programming (iterSOCP) scheme for designing an allpass digital phase-equalizer in the minimax sense. That is, the maximum absolute error of the phase response (maximum phase-error) is to be minimized. This iterSOCP scheme simplifies the minimax design problem as an iterative SOCP problem, and this minimax design problem is solved by utilizing an SOCP solver to find the coefficients of the allpass phase-equalizer. It should be noted that the solution is always a sub-optimal solution due to the non-linear feature of the design problem itself. We will use an example to demonstrate that the improved iterSOCP minimax design results in more accurate design results than other design techniques such as the linear-programming design and other iterSOCP designs.
