  • A survey on continuous-time modulators : theory, designs and implementations

    Creator:
    Gao, Xiaoran
    Abstract:
    Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...

  • Multi-antenna OFDM systems in the presence of phase noise and doubly-selective fading

    Creator:
    Zhang, Yu
    Abstract:
    Orthogonal frequency division multiplexing (OFDM), which has been very attractive for future high rate wireless communications, is very robust to channel multipath fading effect while providing high transmission data rate with high spectral efficiency. Multiple antennas can be combined with OFDM to increase diversity gain and to improve spectral efficiency...
