System Resource Allocation of TD-SCDMA Terminal Based on SDR Platforms

TD-SCDMA terminal is a hot research in China in recent years. To solve a problem that SDR (Software Defined Radio) hardware resource is insufficient, a system resource allocation algorithm of TD-SCDMA terminal based on SDR platforms was proposed. Several SDR hardware platforms were analyzed, and TD-SCDMA terminal processing chains resource model was established. Each function module of the TD-SCDMA terminals was mapped to the SDR platform by the rate allocation of system resource algorithm, t-mapping algorithm and cost function, and the mapping cost was calculated. Simulation results showed that the Heterogeneous platform architecture of SDR and the allocation of the hardware processing power were more reasonable than others, so the utilization of Software Defined Radio hardware resource is improved.
