Design of digital transceiver unit based on multi-channel signal synthesis and new filter combination

With the progress of science and technology, the digital receiver has been widely used in communication, radar, navigation system, electronic warfare system and enemy identification system. A new design of digital transceiver unit is proposed: A new method of signal synthesis and the use of cascading Invsinc filter and CIC filter in digital down conversion to achieve decimation and deceleration; can effectively reduce the interference between transmit signals, system resource consumption and structure complexity, and improve the computing speed of digital transceiver system. The programmable logic gate array (FPGA) is used to realize the digitalization and software design of the system.
