| Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 84 === In this thesis, a timing recovery method is proposed for
8-VSB and 64-QAM digital signals. We desire the recovered
timing for the receiver operationhave an accurate frequency. The
simulation results show that the requirementis achieved. The
timing recovery circuit processes the data signal itself,
noadditional preamble or discrete tone is required. We will
operate the timingrecovery in the baseband and some modification
prevents the interaction withcarrier recovery is also proposed.
We implement the proposed timing recoverycircuit in discrete
components and construct a filter and some control circuitin
FPGA.
