This study demonstrates a signal‐to‐noise ratio (SNR) analysis and estimation algorithm for efficient phase noise mitigation that can be practically applied to single‐carrier frequency‐domain‐equalisation (SC‐FDE) systems that operate in millimetre‐wave bands. First, the effect of phase noise in SC‐FDE systems is investigated on each of the packet reception processes, namely, channel estimation, SNR estimation, and data‐field reception. According to the analysis, an SNR estimation algorithm is proposed. The performance of minimum‐mean‐square‐error equalisation and conventional phase noise mitigation algorithm can be enhanced using the proposed SNR estimation. The effectiveness of the proposed analysis and SNR estimation algorithm is verified through the link‐level simulation. Compared with the conventional SNR estimation and the iterative phase noise mitigation algorithms, the proposed algorithm provides a lower packet‐error rate without any iterative decoding process.
