Summary:A multi-channel synchronization technique is proposed in this article in order to solve the problem that it is difficult to implement high-speed sampler and multiplier in case of using current hardware. This paper introduces wide-band digital down converter based on mixer post-placed structure, radical poly-phase structure, lease common multiple structure and special parameter structure. Then, multi-channel finite impulse response(FIR) filter design and implementation is given. It focus on least common multiple method(LCM) and poly-phase structure based on special parameters. Afterwards, a common method to realize an ultra wide-band(UWB) signal DDC is given. The high-speed serial data convert to parallel data. In the end, validity of the method is testified by simulation.
