Abstract

As a crucial role in scheduling for the TD-LTE system, the Physical downlink control channel (PDCCH) assigns variable resources to the uplink and downlink transmission. Based on the consideration of the structure of PDCCH multiplexing data, this paper proposes an improved blind detection algorithm for the PDCCH in the TD-LTE system. The most remarkable difference from the conventional blind detection algorithms is that our proposed algorithm requires the preprocessing on the PDCCH multiplexing data in a determined search space. The simulation results demonstrate that our proposed algorithm can effectively reduce the average number of PDCCH blind detections.
