%X Aiming at multi-user massive multi-input multi-output systems with jammer under spatial correlation channel, where the system spectral efficiency performance of the base station with low-resolution analog-to-digital converters (ADCs) is studied. Establishing spatial correlation channel by combining exponential Toeplitz correlation models, utilizing the additive quantization noise model and the maximum ratio combination algorithm, a closed expression of the spectral efficiency is derived. The system spectral efficiency under ideal/non-ideal channel state information is analyzed thereafter. Simulation shows that the spectral efficiency will have a saturation effect as the transmit power of the user and the resolution of the ADC increase; when the transmit power of the user is less than the transmit power of the jammer, the influence of the jammer on the system is dominant; when the transmit power of the user is greater than the transmit power of the jammer, it can effectively suppress the influence of the jammer on the system.
