| Abstract | For improved Quality of Service (QoS) under high mobility conditions where channel is fast fading frequency-selective, Orthogonal Frequency Division Multiplexing (OFDM) technique is in next generation 3G and 4G mobile standards. In OFDM, frequency selective channel is divided in flat fading channels of smaller bandwidths. In this paper MATLAB Monte Carlo Simulations are performed for performance evaluation of OFDM multi-carrier transmission scheme for two wireless channel parameters: Channel Impulse Response (CIR) Samples and number of multi-path channel taps. The performance is determined in terms of Bit Error Rate (BER). By increasing channel length and multi-path channel taps not only performance is degraded but also complexity of receiver is increased. |
