Abstract :
A 2-level FSK digital demodulator with CORDIC algorithm for digital-IF receiver is presented. The 2-level FSK noncoherent detector is designed based on counting the zero crossing points using new noise elimination technique. Synchronization control information is extracted from the amplitude signal through setting protection parameters. The output BER is 0.01% for input SNR of 1 dB with frequency offset 0.1 MHz. The digital-IF receiver including demodulator is implemented based on Xilinx Virtex-II XC2V3000-6FG676 FPGA.
