- Abstract
- The performance of Hpi system is dramatically degraded due to the ICI induced by the phase noise; the conventional channel estimator can't combat the ICI. Based on the preamble symbols and pilot subcarriers of the frame, the joint algorithm of the channel estimation and equalizer is presented .The simulation results show that the proposed algorithm can improve the performance of the system by canceling the ICI partially. Meanwhile, the emulation results show that the proposed algorithms improve the system performance dramatically compared with the conventional scheme.
