Abstract :
A 2-level FSK digital modems with CORDIC algorithm for family network is presented. The noncoherent detector is designed based on counting the zero crossings using new noise elimination technique. Synchronization control information is extracted from the magnitude signal through setting protection parameters. The output BER is 0.01% for input SNR of 1dB with frequency offset of 0.1MHz. The design is implemented with Xilinx VirtexII XC2V1000-4FG256 FPGA
