An Algorithm of Software Defined Radio Channel Processing Based on FPGA

A SDR (software defined radio) channel model is put forward in the paper. It is shown that the model will be a multiple FIR filters bank for different frequency bands. Base on the model, a distributed algorithm is deduced by the formula which is suitable for FPGA to achieve the multiple FIR filters bank. At last, the block diagram for FPGA to realized the distributed algorithm is presented which can implement the SDR channel processing.
