A novel digital signal processing (DSP) scheme for special‐shaped circular (7,1) modulated signals based on quasi blind carrier phase estimation (QBCPE) is proposed. The results show that applying 0.33‰ overhead QBCPE provides similar performance as 3% training sequence data‐aided equalization of least mean square (LMS) algorithm.
