Abstract In a method for converting a frequency band signal in accordance with various embodiments, the method may comprise: an operation of converting a frequency band signal into a similar frequency band signal through an encoding part of an autoencoder; an operation of converting the similar frequency band signal into a similar time band signal through an inverse frequency conversion part; an operation of converting into the similar time band signal through a vocoder encoding part and transmitting thereof to the vocoder decoding part; an operation of converting the channel signal into the similar time band estimation signal through the vocoder decoding part; an operation of converting the similar time band estimation signal into a similar frequency band estimation signal through a frequency converting part; and an operation of converting the similar frequency band estimation signal into a frequency band estimation signal through the decoding part of the autoencoder. Therefore, the present invention is capable of improving a security of a communication environment. 다양한 실시 예에 따르면, 주파수 대역 신호를 변형하기 위한 방법에 있어서, 자기부호화기의 부호화부를 통해 주파수 대역 신호를 유사 주파수 대역 신호로 변환하는 동작; 주파수 역변환부를 통해 상기 유사 주파수 대역 신호를 유사 시간 대역 신호로 변환하는 동작; 보코더 부호화부를 통해 유사 시간 대역 신호를 채널 신호로 변환하여 보코더 복호화부로 전달하는 동작; 상기 보코더 복호화부를 통해 상기 채널 신호를 유사 시간 대역 추정 신호로 변환하는 동작; 주파수 변환부를 통해 상기 유사 시간 대역 추정 신호를 유사 주파수 대역 추정 신호로 변환하는 동작; 및 상기 자기부호화기의 복호화부를 통해 상기 유사 주파수 대역 추정 신호를 주파수 대역 추정 신호로 변환하는 동작을 포함할 수 있다
