Digital Satellite Receiver for Wideband Multi-Rate Ka-Band Communications

This correspondence presents the architecture of a high-speed low-complexity digital receiver for wideband satellite communications supporting multiple baud rates, ranging from 10 to 200 MBaud. The design of the modem is based on the Cascaded Integrator-Comb (CIC) scheme which exploits a parallel processing so as to provide an outstanding decimation agility. Eventually, bit error rate (BER) performance of the multi-rate receiver are assessed by floating-point simulations
