A transmission channel signal processing system for multichannel digit TR subassembly

The utility model discloses a transmission channel signal processing system for multichannel digit TR subassembly, it includes data input interface, complex coefficient FIR wave filter and digital upconverter, the data input interface input is passed through to baseband IQ data, it carries out the up -conversion to get into digital up converter through complex coefficient FIR post -filter, digitup converter includes one -level FIR interpolation filtering ware, 2 the interpolation filtering ware is partly taken to the level, 1 level frequency converter and one -level first detector, basebandIQ data through complex coefficient FIR post -filter loop through one -level FIR interpolation filtering ware, 2 the level is partly taken and is transmitted the first detector behind the interpolation filtering ware to, carry out the mixing with the sin (wt) and the cos (wt) of quadrature through frequency converter conversion, baseband IQ data transmission after the mixing produces the module tothe linear polarization wei
