摘要：

One of the most popular blind equalization techniques is the Constant Modulus Algorithm (CMA), and it has gained popularity in the literature and in practice because of its LMS-like complexity and its robustness to non-ideal, but practical, conditions. Although CMA has been well-studied in the literature, these analyses have typically implemented the algorithm using "infinite" precision arithmetic. The motivation for this paper is a VLSI implementation of a high data rate, fractionally spaced, linear forward equalizer whose taps are adjusted using CR;ZA. In this paper we examine how implementing CMA using finite bit precisions affects the algorithm's performance.
