One kind of channelized receiver structure applied to software radio platform

The digital channelized receiver is an efficient way to deal with broadband signal. In this paper, one kind of channelized algorithm based on poly-phase filter is derived. We discussed the realization of a multi-channel receiver applied to the software radio platform in details. The computing core of this platform is FPGA. Simulation result of the channelized receiver is given. The test in practical condition is also done. The results show that our design is available and practical.
