Abstract:

In this paper, we put forward a novel time slot structure, which is made up of four parts: pre-pilot, data, post-pilot and guard time. Based on this novel
time slot structure, the interpolation of channel estimation can be achieved within every TDD time slot. The simulation results show that BER performance can be improved significantly when the system experiences fast fading.

Key words: TDD, fast fading, time slot structure, high-order interpolation, channel estimation
