A promising technique for the next 6G network is terahertz (THz) communication. To reduce the severe attenuation and excessive power utilization, massive MIMO(mMIMO) accomplished by hybrid precoding has been broadly used for THz. However, frequency independent phase shifters as to be the typical hybrid precoding architecture cannot survive to the beam split effect into THz mMIMO effected by the high number of antennas and bandwidth. A full bandwidth array gain loss is caused by the beam split effect. In this paper, the beam split effect causes a considerable performance loss in beam tracking algorithms developed for narrowband with the typical hybrid precoding. To alleviate this problem, a DPP(delay phase precoding) facing THz massive MIMO was recently developed. We verify the beam tracking system to easily manage the angular coverage of frequency based beams through bandwidth. By analysing the array gain loss generated through beam split effect in terahertz mMIMO systems, the severity of the problem may be shown and quantified. We use a beam tracking method suggest to track numerous users physical directions at the concurrent in always lot to generate many beams. The suggested beam track can concurrently track many user physical directions by utilizing numerous frequency based beams generated through radio-frequency chains. The analysis exhibits that the suggested system can attain the sum rate performance with short beam training and considerably reduce the array gain the loss effected through beam split effect. We suggest TTD(true time delayer) to recognize frequency based phase shifters on appreciating the idea of Delay Phase Precoding.
