Abstract :
In order to accelerate the mapping of Distributed Virtual Resource Block (DVRB) to Distributed Physical Resource Block (DPRB), a low computational complexity realization algorithm is proposed. It calculates the sorted index of PRBs directly, and the DPRB index can be got by cascading mapping module results of the plurality of VRBs. Its implementation is simple and easy to realize in the TMS320C64×DSP. The running results show that the proposed algorithm can save lots of simulation time. Meanwhile, the feasibility and effectiveness of this betterment method have been verified. The program has been applied to the development of TD-LTE RF conformance testing system.
