Abstract:
1. A system for implementing beam forming for a single user, and this system comprising: a detection unit, a null widening calculation unit and a beam forming unit; wherein, the detection unit is for detecting an uplink signal intensity, and obtaining a first detection threshold and a second detection threshold; and inputting the first detection threshold and the second detection threshold into said null widening calculation unit; the null widening calculation unit is for calculating a first beam forming weight corresponding to the first detection threshold and a second beam forming weight corresponding to the second detection threshold by using a null widening algorithm according to input the first detection thresholds and the second detection threshold; the beam forming unit is for setting directions of beam forming respectively according to the first beam forming weight and the second beam forming weight and implementing downlink beam forming in a condition of sending two data streams at a same time for a same one user; wherein said first detection threshold specifically is a first direction of arrival DOA the detection unit is further for performing detection according to an uplink SRS, and obtaining the DOA said null widening calculation unit is further for calculating a first beam forming weight W
