    Abstract: 由於目前使用的頻段愈來愈擁擠,5G 系統為了要達到更高的傳輸
    法可以減少計算複雜度並且提供可靠的效能。;Since the frequency bands currently used are becoming more crowded,
    in order to achieve higher transmission rates, the 5G system has begun to
    look for millimeter waves with wider bandwidth. Therefore, in recent years,
    the design of millimeter wave systems has gradually received attention.
    This thesis proposes schemes about how to cancel the effect of
    interference on the millimeter wave system, while the millimeter wave
    system suffers from strong interference. Due to the limitation of millimeter
    wave transmission characteristics, a huge number of antennas must be used
    to achieve a longer transmission distance. In order to reduce the complexity
    and the energy consumption of the hardware design, the hybrid
    beamforming technique that combines analog and digital beamforming
    must be used. The received signal will go through the analog terminal first,
    and the first step can be performed on the analog terminal to cancel part of
    the effect of the interference on the system. The processed signal will then
    enter the digital terminal, and the digital terminal can effectively suppress
    the remaining interference. Generalized sidelobe canceller is a commonly
    used method for interference and noise cancellation, and thus we apply it
    in the digital beamforming combined with the multistage Wiener filter.
    Under the condition of limited samples, the dimensionality reduction
    algorithm of the multistage Wiener filter can reduce the computational
    complexity and effectively provide better performance.
