With the increasing density of communications systems in the wireless spectrum, the ability for two communications systems to share the same frequency space will become critical. To accommodate this, it becomes necessary to understand the nature of impairments introduced when two systems share the same spectrum. Traditionally, the performance of a communication system is analyzed in the presence of random interfering noise (Gaussian, Rayleigh, etc.), specific channel impairments like multipath or fading, or narrowband interferers. This work will focus solely on the wideband interference of one communication system on another. Wireless communications systems are increasingly bifurcating along two primary paths: OFDM and Spread Spectrum. This thesis will analyze three parameters of an OFDM system to understand their impact on a forward-path, single-transmitter DSSS system, both analytically and empirically. Ultimately, the effect of these parameters on probability of error and a method to reject the interference of each system on the other will be presented.
