Abstract :
To characterize the transmit modulation quality of Physical Uplink Shared Channel (PUSCH) in Long Term Evolution (LTE) system more efficiently and integrally, it is necessary to measured the Error Vector Magnitude (EVM) .In this paper, we research EVM measurement algorithm to correct the transmit modulation symbols quality of PUSCH, and deduce the method of calculation its. In addition, we gave the MATLAB simulation and compared with the bit error rate (BER).
