Noncoherent Amplify-and-Forward Cooperative Networks: Robust Detection and Performance Analysis

  title={Noncoherent Amplify-and-Forward Cooperative Networks: Robust Detection and Performance Analysis},
  author={Peng Liu and Saeed Gazor and Il-Min Kim and Dong In Kim},
  journal={IEEE Transactions on Communications},
We develop closed-form generalized likelihood ratio test (GLRT) sequence detectors for multi-relay amplify-and-forward (AF) cooperative networks employing M-ary differential phase-shift keying (M-DPSK) and noncoherent M-ary frequency-shift keying (M-FSK). The proposed detectors achieve robust performance in a wide range of fading environments where prior knowledge of channels, signal powers, noise variances, and relay functionalities is unavailable to the destination. A comprehensive error… CONTINUE READING
