    • 2008, Byeong Gi Lee, Sunghyun Choi, Broadband Wireless Access and Local Networks:
      In the case of the ZF detector, we suppress the interference among the transmit streams by multiplying the received signal vector y with the Moore-Penrose pseudo-inverse of the channel matrix []
    • 2010, Dayan Adionel Guimaraes, Digital Transmission, page 348:
      However, due to its simplicity, ZF equalization is a good choice when the channel is known and fixed, and also when there is no frequency notch in the channel frequency response []
    • 2013, Academic Press Library in Signal Processing, page 308:
      Thus, the importance of the upper bound is in showing that even in the most optimistic case, the achievable rate cannot exceed the ZF rates by more than 10%.
