Research of Channelized Transmitter based on Polyphase Filter

The paper,based on implementation principle of the real signal channelized transmitter,deduces the calculation formula for the center frequency and the channel space of this real channel;then the polyphase filters structure of the decimator and interpolator,thus to establish the mathematical model of channelized transmitter based on polyphase filters;finally,discusses the feasibility of this highly efficient real signal channelized transmitter based on polyphase filters and gives two computer simulations of this transmitter.Simulation results indicate the correctness of this transmitter mathematical model and the real-channel center frequency formula.
