Constant modulus equalization algorithm (CMA) is widely used for mitigating inter-symbol interference (ISI) in various communication systems, for its robustness and low computational complexity. In practice, signed error CMA may be adopted to simplify the implementation. However, the simplification severely degrades its steady state performance. In this paper, a detailed analysis is taken to compare the mentioned two algorithms in Field Programmable Gate Arrays (FPGA) implementation. Furthermore, a novel error function is proposed for the high speed implementation consideration. Numerical simulation demonstrates that the proposed algorithm behaves much better than the reference with similar computational complexity, which makes the proposed algorithm more suitable for the area of high speed applications.
