In this paper, we derive the Symbol Error Probability (SEP) of cooperative systems using Amplify and Forward (AF) or Decode and Forward (DF) relaying. In AF relaying, each relay amplifies and retransmits to the destination the received signal from source. The destination combines the signals received from all relays and the source using a Maximum Ratio(More)
—The co-channel cell interference (CCI) becomes the major performance degradation factor for multi-cell OFDMA systems. In this paper, we propose two fractional frequency reuse (FFR) schemes that can efficiently avoid the CCI in the cell edge: scheme I where each cell is divided into two regions: the central region and the edge region. In the central region,(More)
