Baseband chip, signal demodulation method, terminal device, storage medium and product

The invention provides a baseband chip, a signal demodulation method, terminal equipment, a storage medium and a product, and belongs to the technical field of wireless communication. The baseband chip comprises a detection module used for respectively carrying out signal detection on a plurality of first signals according to correlation coefficients among the plurality of first signals and a signal-to-noise ratio of each first signal to obtain first soft decision signals respectively corresponding to the plurality of first signals, the signal detection comprising at least one of linear detection and non-linear detection; and the decoding module is used for decoding the first soft decision signals respectively corresponding to the plurality of first signals. According to the baseband chip, a signal detection mode is matched with a correlation coefficient and a signal-to-noise ratio of a first signal, and a first soft decision signal with high accuracy can be obtained; the first soft decision signal is decoded
