Abstract

In this paper, the performance of the multiple-shift correlation (MSC) based blind channel equalizer (BCE) under channel order mismatch due to small head and tail channel coefficients is investigated. The analysis results show that the output signal-to-interference plus noise ratio (SINR) of the MSC-based BCE is degraded due to the small channel coefficients. The performance degradation is function of the optimal output SINR, the optimal output power, and the control vector. In such channel order mismatch environment, this paper proposes a simple but effective iterative method to improve the performance. Analysis of the iterative method is also performed. Simulation examples are demonstrated to show the effectiveness of the proposed method and the analyses.
