Abstract
A noise cancellation device for a wireless communication system is provided to include wireless communication devices each using a digital phase modulation and each performing half-duplex communication. The wireless communication devices is configured as an array, and the noise cancellation device is provided for suppressing an wrap-around signal from other wireless communication device by combining a cancellation signal obtained by controlling at least one of a phase and an amplitude of a transmission carrier signal with a received wireless signal based on a baseband signal of the received wireless signal. The noise cancellation device includes a controller configured to determine whether a number of bits per one frame of the baseband signal to be transmitted is an odd number or an even number, and to invert the cancellation signal when the number of bits per one frame of the baseband signal to be transmitted is an even number.
