Executive Summary

This paper suggests a modified millimeter wave wireless system using Orthogonal Frequency Division Multiplexing (OFDM) technique, integrated with optical fiber as a feeder network. Here it has investigated how well OFDM performs when transmitted over the wireless channel and Multi Mode Optical Fiber (MMOF) channel for various S/N values & fiber length respectively. Simulated performance shows that as the SNR is increased the signal gets less affected by noise; hence there will be fewer errors in decoding. For SNR greater than 12 dB, there is no significant difference observed in the received constellation. Therefore, it is not recommended to increase the SNR above 12 dB, as it results in unnecessary enhancement of the system complexity.
