Abstract:Millimeter‐wave (mmWave) and massive multiple‐input multiple‐output (MIMO) technologies are critical in current and future communication research. They play an essential role in meeting the demands for high‐capacity, high‐speed, and low‐latency communication brought about by technological advancements. However, existing mmWave channel estimation schemes rely on idealized common sparse channel support assumptions, and their performance significantly degrades when encountering beam squint scenarios.
