碩士 === 大同大學 === 電機工程學系(所) === 98 === ABSTRACT This thesis presents a method of two-way HFC (Hybrid Fiber Coaxial) cable network can be utilized effectively in every home. The system of OFDM will be realized in the DOCSIS 3.0 structure of the upstream in the transmitter and the receiver. The OFDM-SCDMA by Verilog language will be implemented. The first step is to use 16QAM and SCDMA in the upstream transmission system and the following step is to implement the OFDM structure by the Radix-4 butterfly controllable circuit and cache memory. We design and simulation of the whole system is achieved through QuartusⅡ 7.0.
