The device for receiving a frequency-shift keying signal includes a front-end circuit, complex differential discriminators, and a recovery circuit. The front-end circuit receives a signal transmitted via a frequency-shift keying channel, and generates the baseband signal of the received signal. The complex differential discriminators have a plurality of orders and use the complex conjugate of the baseband signal of the received signal. The recovery circuit recovers symbols by applying a maximum likelihood sequence estimation (MLSE) technique to the output values of the complex differential discriminators having the plurality of orders."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for receiving frequency-shift keying signal","description":"Disclosed are a method and device for receiving a frequency-shift keying signal.
