Wideband fft channelizer

An appearance piece is compact, the multi-channel wireless communication transceiver structure for broadband signal processing, wherein the is overlapped additive or multiphase signal processing function, comprising a sampling thereof. The receiving part for wherein multiple communication frequency channels and output to represent wherein multiple frequency communication channel contents the digital signals. The receiving part comprises a FFT-based the channel parallel, a digital signal for processing broadband digital receiver and output channel corresponding output to the first group of multiple digital signal processing device, multiple operation unit (e.g., demodulation) are multiple digital channel signal and a flexible with multiple digital channel signal and corresponding output port, so that the number of allocating to a voice of temperature-control/in digital network. A transmission, the transmission part comprises multiple digital signal processor, a corresponding flowing the voice (the plurality of the different channel transmission are respectively/data) and communication signal by. Solution processing circuit (, coding) and output providing to a counter FFT mixer. The mixer FFT emitting to the multi-frequency communication channel of broadband transmitter providing a comprehensive the multiplex signal. Each channel parallel and mixer available on the additive or the multi-phase realizing filter.
