Abstract： |
The invention belongs to digital transmission technology area. Its characteristic is: it put forward a new test model for the OFDM multi-carrier modulation system. This model sees the data stream from the inchoation of the modulation system and the data stream from the receiver as linear channel with the white Gaussian noise. Namely, we can describe the data stream from the inchoation x(n) and the data stream from the receive r(n) by r(n)=h(n)*x(n)+v(n). Here, '*' stand for linearity convolution operation. h(n) stand for test model channel's impulse response. v(n) stand for the linear convolution system's noise and the data disturbance. Propose a precise measuring model method according to this model. Its characteristic is that it carries on model parameter estimate when using LPVR testing system to transmit data. |
