Abstract
In this thesis, standard specification study, functional simulation, architecture design and circuit design along with FPGA implementation of a baseband communication system for HomePlug AV (HPAV) applications is presented. HPAV is a standard for the powerline communication system. A baseband communication system depending on HPAV standard is proposed in this thesis. A physical layer (PHY)of basedband communication system including transmitter, channel model, and receiver is simulated and implement. Discrete multitone modulation (DMT) is used in the baseband communication. This modulation is one kind of OFDM system for wire communications. According to HPAV standard, the 3072-point FFT processing architecture is adopt and it is not the power of two. The prime-factor algorithm (PFA) is used to implement the FFT processing architecture. The mapper is high order (1024-QAM) in HPAV standard. The structure of the preamble symbol matches the request of HPAV standard and supports enough information to receiver. In order to verify the proposed design, the channel model is used in [1]. The channel effect includes Noise, disturbances, multipath effect and, sample frequency offset(SFO). The circuit design is implemented and verified by FPGA emulation. The pattern generator (PG) is used for input pattern generating and the logic analyzer (LA) is used for output analysis.
