%X A kind of Dual-mode Constant Modulus Algorithm(DCMA) based on fractionally-spaced equalization for blind equalization is presented to compensate the defects of the Constant Modulus Algorithm(CMA) and the Signed-Regressor CMA(SR-CMA). DCMA combines the conventional CMA and SR-CMA, and the switch process between CMA and SR-CMA is realized by decision circle ring which boundary is decided by the signal-to-noise radio. Computer simulation proves that DCMA is more robust than SR-CMA and more computationally efficient than CMA, and its residual mean-square error is lower than that of CMA and SR-CMA.
