Inter-user　interferences　(IEIs)　and　intra-user　interferences　(IAIs)　may　degrade　the　quality-of-service　in　JT　(joint　transmission)-CoMP　(coordinated　multi-point)　systems.　Interference　alignment　(IA)　with　prefect　channel　state　information　(CSI)　can　efficiently　mitigate　these　interferences.　However,　in　realistic　systems,　the　effect　of　IA　is　obviously　decreased　via　channel　uncertainty　with　channel　estimation　and　quantization　errors.　In　this　case,　we　propose　a　novelly　robust　precoder-and-receiver　design　scheme　with　IA　(NRIA)　for　interference　suppression　and　channel　uncertainty　restraint.　In　the　NRIA,　we　first　utilize　precoding　method　to　suppress　the　IEIs　to　each　user　generated　by　the　users＇　actually　acquired　channels.　Second,　the　receiver　of　each　user　is　devised　to　alleviate　the　impact　of　IAI　and　channel　uncertainty.　Unlike　the　existing　MU-MIMO　schemes　which　introduce　the　statistical　or　bounded　information　of　the　above　errors,　the　NRIA　is　a　local　scheme　for　JT　and　contains　the　instantaneous　information　of　channel　uncertainty.　The　instantaneous　information　can　be　abstracted　through　installing　and　sending　special　transmit　signals　from　base　stations　to　users　without　exorbitant　overhead.　The　NRIA　doesn＇t　include　any　iteration,　moreover,　it　can　suppress　interference　and　improve　robustness　compared　with　just　using　statistical　or　bounded　information　of　channel　uncertainty.
