Abstract

In this paper an investigation to the performance of single input single output (SISO) – orthogonal frequency division multiplexing (OFDM) system in both additive white Gaussian noise (AWGN) and multipath fading channels in the presence of jamming is provided. The effects of two types of jamming techniques; Partial band and broadband jamming on the performance of OFDM system are presented and investigated. The impact of symbol time offset on the performance of OFDM system is also investigated in the considered channels. A closed form analytical expression for the symbol error rate for different values of the carrier frequency offset is derived.
