  • Patent number: 8111786
    Abstract: A signal converter. The signal converter converts an analog inphase signal and an analog quadrature phase signal into a digital baseband inphase signal and a digital baseband quadrature phase signal. The analog inphase signal and the analog quadrature phase signal are orthogonal to each other and are carried in a predetermined intermediate frequency. The digital baseband inphase signal and the digital baseband quadrature phase signal are carried in zero frequency. The signal converter comprises a signal combiner combining the analog inphase signal and the analog quadrature phase signal to obtain an analog combined signal, an analog to digital converter converting the analog combined signal to a digital combined signal, and a signal separator separating the digital combined signal to obtain the digital baseband inphase signal and the digital baseband quadrature phase signal.

  • Publication number: 20110051635
    Abstract: A communication method employed in a wireless communication system including a first communication device and a second communication device is provided. The communication method includes: setting up a connection between the first and second communication devices; after the connection is set up, checking if both the first and second communication devices provide a symbol mapping function for converting a first modulation/demodulation to a second modulation/demodulation different from the first modulation/demodulation; and when both the first and second communication devices provide the symbol mapping function, using the second modulation/demodulation to replace the first modulation/demodulation so that each of the first and second communication devices communicates with each other by using the second modulation/demodulation.

  • Publication number: 20090310717
    Abstract: A signal converter. The signal converter converts an analog inphase signal and an analog quasdrature phase signal into a digital baseband inphase signal and a digital baseband quadrature phase signal. The analog inphase signal and the analog quadrature phase signal are orthogonal to each other and are carried in a predetermined intermediate frequency. The digital baseband inphase signal and the digital baseband quadrature phase signal are carried in zero frequency. The signal converter comprises a signal combiner combining the analog inphase signal and the analog quadrature phase signal to obtain an analog combined signal, an analog to digital converter converting the analog combined signal to a digital combined signal, and a signal separator separating the digital combined signal to obtain the digital baseband inphase signal and the digital baseband quadrature phase signal.
