Broadcasting) is 9.953 Mbps much greater than DAB (Digital Audio Broadcasting). It is necessary to use better signal processing algorithm to improve the performance of DVB receiver. Hence, we propose some methods:(1) To optimize Reed-Solomon and Viterbi decoder;(2) To use parallel process instructions;(3) To Reduce FOR Loop and IF Branch, etc. After these modifications, the software radio in real-time reception based on PC can be implemented. In summary, we demonstrate a software receiver which operates at an acceptable real-time decoding speed.
