Performance evaluation of a 3D ray tracing model in urban environment

During the last years, multiple-input multiple-output (MIMO) and OFDM systems emerged as a solution for the high data link in radio communication. The performances of these systems depend not only on the propagation channel path loss but also on the delay and the angular spread of the channel impulse response [1]. Ray-tracing or ray-launching models have the advantage to predict all channel large-scale parameters coherently. Thus, these models may be implemented in future wireless engineering software package.
