Abstract:
The total data rate of DVB (Digital Video Broadcasting) is 9.953Mbps 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.
