Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) is at the heart of current wireless standards and is the main modulation scheme envisioned for use in future generations of wireless communication systems. In this paper we study the performance of precoded OFDM systems in the presence of intentional jamming. Specifically, we consider OFDM systems with sub-band Hadamard precoding for which we derive the expression of the signal-to-jammer+noise-ratio (SJNR) and study how jamming signals with different bandwidths affect the bit error rate (BER) performance of the system.
