  4. Abstract:
  5. The vertical plane launching ray tracing method has been applied for a real urban scenario and the delay characteristics of received signals in the overall coverage area have been extracted. Using these parameters, an equivalent channel impulse response (ECIR) has been introduced for the overall coverage area. For an orthogonal frequency division multiplexing system, the optimum guard interval, which maximises the number of points with symbol error rate less than a threshold, has been simulated. Using the defined ECIR, the optimum guard interval could be analytically extracted
