Description
Summary:	Digital modulation based on FSK is widely used in HF data communication. This is due to simplicity in implementation by noncoherent detection and robustness due noise and phase synchronization error. Hardware based design using FPGA can reduced system size. The proposed modulation integrates both the transmitter and receiver modules into a single FPGA. Further reduction in components is achieved by adopting a multiplierless and parallel algorithm at the receiver module. This is proven by comparing with conventional noncoherent detection algorithm.
