A Novel Detection Scheme to Mitigate the TD-LTE Interference

摘要：

In this article, a novel detection scheme will be introduced into the CR system based on the Time Duplex-Long Term Evolution (TD-LTE) scheme, in which radar system is the primary user. If the CR nodes carry on the on-line energy detection to the radar signal, it will be subject to the interference originated from the TD-LTE systems Base Station (BS) 1. We propose a new detection program employed only in the TD-LTE uplink timeslots. In this program, the interference, which is coming from the TD-LTE systems User Equipment (UE) 2, may be weaker than it originated from BS. At the same time, the performance will be enhanced by accumulating multiple coherent detecting results. Through theoretical analysis and simulation, the feasibility of the new program has been verified.
