Title: MODULATION MODE DETECTION METHOD AND DEVICE
Abstract:
Disclosed are a modulation mode detection method and device. Embodiments of the present invention provide a modulation mode detection method and device, for use in solving the problem of difficulty in productization due to high complexity of an existing modulation mode blink detection scheme. The method comprises: performing joint detection on a receive signal vector according to a channel matrix for each candidate modulation mode to obtain accumulated branch metric vectors corresponding to each RE; performing summation on a minimum value in the accumulated branch metric vectors corresponding to each RE to obtain a minimum accumulated branch metric corresponding to the candidate modulation mode; and determining a minimum value from the minimum accumulated branch metrics corresponding to all the candidate modulation modes and determining the modulation mode corresponding to the determined minimum value as the modulation mode used by an interference cell.
