| Abstract: | To improve flexibility of the traditional software defined radio development and reduce the cost,general-purpose processor software defined radio(GPP-SDR) platform is adopted to study software development and optimization of TD-HSDPA high-speed physical channel including HARQ functional module.By optimizing the receiver code,the efficiency of software is greatly improved.Latency measurement results demonstrate that this software implementation can realize real-time TD-HSDPA transfer and support the physical channel protocol stack running on the GPP-SDR platform efficiently.HARQ simulation results for this design are also given to validate its performance. |
