| Abstract: | We design a noise monitoring and suppression system for hybrid fiber coax reverse channel. In the given system S3C4510B ARM is adopted to build Ethemet network application system, TMS320C6713B DSP is utilized to analyze the real-time spectrum of large amount data and FPGA is used for high-speed caching as well as logical control of system. Experimental results demonstrate that our proposed system can make real-time collection and high-speed processing of signals in HFC reverse channel correctly and effectively maintain the performance in the reverse channel of HFC. |
