Abstract

The maximum average achievable rate and the outage probability of the opportunistic scheduling over the cyclically prefixed (CP) single-carrier (SC) downlink transmissions are analyzed. In the user terminal, the QR-decomposition (QRD)-based receiver is employed to maintain the multipath diversity gain. Based on the proposed receiver, closed-form expressions for the maximum average achievable rate and the outage probability can be derived using the property of the circulant matrix. In addition, the outage diversity gain is obtained at high average signal-to-noise ratio (SNR). Simulations verified the derived analysis.
