Collision Model for the Bit Error Rate Analysis of Multicell Multiantenna OFDMA Systems
Abstract— A multicell system which supports multiple antennas and OFDMA modulation/access is considered in this paper as conforming IEEE 802.16-2005 standard. Focusing on the uplink, the system performance is severely hampered by the out-of-cell interference due to the frequency reuse. Here we analytically assess the error probability by employing a collision model to describe the non-stationarity of the out-of-cell interference due to random subcarriers permutation as prescribed by PUSC mode. The collision model permits an accurate analysis both of uncoded and coded transmissions. Two different decoding strategies are investigated according to the amount of information available at the receiver. Simulation results corroborate the proposed analysis.
